1187475 - CKEditor widget stops working as of FF 39 (or maybe lower)

Status: RESOLVED DUPLICATE of bug 1181130

(Firefox :: Untriaged, defect)

Description

[cFreed]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0
Build ID: 20150630154324

Steps to reproduce:

Go to the CKEditor widget demo page: http://ckeditor.com/demo#widgets.

A) In the first widget sample, chapter "Simple box template":
A1. click anywhere inside one of the two sub-boxes
A2. then click elsewhere in the same sub-box
A3. again click anywhere in the same sub-box
A4. be sure to be in the A3 situation then click and drag to select part of text

B) In the third widget sample, chapter "Enhanced image":
B1. click anywhere in the text of the bottom sub-box
B2. then click elsewhere in the same sub-box

I discovered this issue today with my own CKEditor widget which behaved like in B above. Then googling I found a recent issue report about behaviour like in A: http://stackoverflow.com/questions/31601251/ckeditor-widget-firefox-bug.

Form me, all these behaviours happen only with Firefox 39 (Windows 7): IE, Chrome and Opera work right.
Regarding my own case, it might be so before FF39 (I didn't use the involved app from one or two months), but the other issue reports precisely FF39.


Actual results:

A1. highlights blue border and positions the caret at the sub-box top-left
A2. the blue border disappears and the caret goes in the text outside of the widget: in fact, the the currently involved sub-box is no longer selected; so it's not possible to insert new content elsewhere than at the very begin of the sub-box
A3. nothing more happens (you can repeat A3 n times without any result; to have this sub-box to react again you must first click outside of it, then inside of it, so we are like in A1)
A4. another part of text, outside of the widget, get selected

B1. highlights blue border and positions the caret at the sub-box top-left
B2. the blue border and the caret disappear (doesn't go elsewhere), and the whole content of the two sub-boxes get selected


Expected results:

A1. normal behaviour
A2. should keep blue border and position the caret at the click location
A3. same as A2, at the new click location
A4. should select the dragged part of text

B1. normal behaviour
B2. should keep blue border and position the caret at the click location

This was already fixed by backing out bug 1132768 in Beta40 and Aurora41 channel.
