This carves out an exception for hard-coded loopback addresses to allow
`ws:` connections from `https:` to allow mixed-mode from secure pages.

This DOM/Web API is entirely irrelevant for desktop use.
We give back the width/height of the root scrollframe of content and
for scale we pass forward our dpp resolution (usually 1.0).
Since we have no "no touch" zones in our content on desktop,. the rest
(origin and offset) is hard-coded to (0,0).
Trying to do a positive check on nested URIs apparently doesn't work,
but the handling could be simplified to just check for non-null mURI
instead - this also fixes plugin loading (which broke with the previous
check).
If a website would nor supply a URI for object loading code, the browser
would crash on a null deref.
This reintroduces the nestedURI check to make sure we have a valid URI.
Youtube's usage patterns have changed regarding video embeds, so we can
remove special handling for the enablejsapi flag.
Applies YouTube embed URL replacement to the path component only.
Per spec, extend escaping of attribute value characters to include
`<` and `>`. We already did this for text fragments, and it makes sense
to apply the same to attribute values. We are at parity with mainstream
that default-escape attribute values this way in current releases.
This changes Rotate{Self}(angle, translateX, translateY) to
Rotate{Self}(rotateX, rotateY, rotateZ) per the spec.
The resulting matrix will be a 3DMatrix
Resolves#2752
This interface inly has a single implementation behind it, which is also
only used in 2 places after the previous commit. That's a lot of
additional complexity and compiler indirection for no good reason.
This change removes the interface and uses direct nsDocShell::Cast calls
instead of going through the interface in the few places left now that
we no longer build on a presentation context for links.
This removes the requirement for there to be a non-null PresShell to
dispatch `Click()` events on `<A>` elements (only), since the exception
to the rule has propagated to the spec.
With these changes it should now be possible do create an anchor and
`Click()` on it from JS without actually first attaching it to the DOM
of the presented document, as abused by scripted downloads in pages
(instead of using the A attribute to custom-name downloads).
Use subject principal as triggering principal in <img> "src" attribute.
Also get rid of the `BeforeMaybeChangeAttr`/`AfterMaybeChangeAttr` dance:
It makes more logical sense for these effects to happen _after_ the
attribute has actually been changed.
In order to tailor certain security checks to the caller that is
attempting to load a particular piece of content, we need to be able to
attach an appropriate triggering principal to the corresponding requests.
Since most HTML content is loaded based on attribute values, this means
capturing the subject principal of the caller who sets those attributes,
which in turn means we need to make it available to `AfterSetAttr` hooks
on all relevant element types.
We're currently fairly vague and inconsistent about the values we provide to
content policy implementations for requestOrigin and requestPrincipal. In some
cases they're the triggering principal, sometimes the loading principal,
sometimes the channel principal.
Our existing content policy implementations which require or expect a
loading principal currently retrieve it from the context node.
Since no current callers require the principal to be the loading
principal, and some already expect it to be the triggering principal
(which there's currently no other way to retrieve), a choice was made
to pass the triggering principal whenever possible, but use the loading
principal to determine the origin URL.
