Bug 1864334 - Make `nsIFrame::MovingCaretToEventPointAllowedIfSecondaryButtonEvent` check whether the right click point is in a selection range first r=emilio!,#dom-core
48 bytes, text/x-phabricator-request
Details | Review

Windows 10 OS
beta 120.0b5

  • Click on 'Write' or 'Reply'
  • 'Write' message window opens.
  • Enter anything in the composing area.
  • Highlight text - single word, sentence or use Ctrl +A
  • Right click on highlighted text

Actual Results
Text immediately becomes not highlighted
Upon Right click menu has 'Undo', 'Cut', 'Copy' and 'Delete' as disabled

Expected REsults
Highlighted text to remain highlighted
Upon right click all menu items to be enabled.

Additional:
tested in 'Troubleshoot Mode' and get same results.
tested in 'Offline' and 'Online' modes and get same result.

Bug is Right click on highlighted text removes the highlight,
so it will not offer 'Undo', 'Cut', 'Copy' and 'Delete' as options.

Confirmed on trunk.

Indeed, I reproduce it in Thunderbird too. Fortunately, I reproduce this bug within Firefox if I load data:text/html,<iframe srcdoc="abc" onload="event.target.contentDocument.designMode='on'"></iframe>.

[Tracking Requested - why for this release]:

This is a serious regression for web apps which use designMode (I'm not sure how may apps using the legacy editor mode) or making <html> content-editable. Perhaps, backing-out bug 1845241 from the release candidate is the most reasonable fix for this in this stage.

The simplest testcase is data:text/html,<html contenteditable>abc</html>

  1. Load data:text/html,<html contenteditable>abc</html>
  2. Do "Select all"
  3. Right click on the selected text
URL: data:text/html,<iframe srcdoc="abc" o... → data:text/html,<html contenteditable>...

If <body> or something which is not the root element is the editing host, this bug is not reproducible.

This is a simple mistake of the previous patch. The code path is originally for
a left click handling. Therefore, there is no check whether the click point is
in a selection range because in that case, left click should collapse selection.
However, the selection should not be collapse when it's a right click in a
selection range because the context menu target is the selection range.

The ui.mouse.right_click.collapse_selection.stop_if_non_collapsed_selection
pref is set to true by default. Therefore, the existence of a non-collapsed
selection has hidden this bug. However, it's set to false, this always
happens. Additionally, editor does not set ancestor limiter of selection if the
root element is editable [1]. I think that we can now remove this special path,
but it's risky. Therefore, this patch just adds the new check into the method.
