[Opera] Selection mangled after apply inline style (CORE-41462)

[Garry Yao]

1. Load any of the default sample page, make the following selection:

   <p>
   	This is so[me <strong>sam]ple text</strong>.</p>
   

2. Apply any of the inline style

• Actual Result: Note the selection is changed.

[Garry Yao]

The bug applies to also any selection that partially cover an inline element, not a regression though.

Seems to WFM in O11/CK3.5

[Garry Yao]

Still in trunk with O11.

[Hallvord R. M. Steen (Opera Software)]

Wondering if this might be related to Opera's bug CORE-3906..

I note that it's a matter of broken selection rendering - try clicking e.g. "Bold" several times. The entire highlighted selection is not bolded and unbolded, only the characters that were actually selected earlier!

[Hallvord R. M. Steen (Opera Software)]

Finally managed to return to this - confirmed it is an Opera bug, and it's now reported as CORE-41462 on our side.

[Frederico Caldeira Knabben]

Even though CORE-41462 is marked as fixed, it is still reproducible.

Unfortunately yesterday I reported the same issue on v4 (#9447) and with the latest Opera 12.02. Except that it happens more often and in both "directions". I'd even say that it completely messes up the usability of the editor.

[Garry Yao]

Ported #9447 from v4 with [7655] as a workaround for this issue.

[Wiktor Walc]

The selection is in fact broken in Opera 12.12 because of this commit ([7655]).

1. Apply e.g. italic style to

<p>
	This is so[me <strong>sam]ple text</strong>.</p>

• ​rev 7654: selection is okay
• ​rev 7655: selection over "sam" is lost

<p>
	This is some <strong>sam[ple text</strong>. You ar]e using <a href="http://ckeditor.com/">CKEditor</a>.</p>

• rev 7654: selection is okay
• rev 7655: selection over "You ar" is lost

I am no longer able to reproduce the issue from TC if I revert [7655] in trunk.

I have checked this on various systems and had the same results as @wwalc - it works as expected on Opera 12.12 from version 3.0 but without this revision.

I'm changing version to trunk rev. [7655] from 3.0

[Frederico Caldeira Knabben]

Reverted [7655] with [7683]. It is not necessary any more.
