Still working in TB 128.

If 128 is generally working for you, does that mean the following reports are also WFM in 128?

• Bug 1907532 - Spell check not working in subject after "Compose Message To" when at least one non-English dictionary is used
• Bug 1907532 - Spell check not working in subject after "Compose Message To" when at least one non-English dictionary is used

Bug 1907532 was confirmed for TB 128 and a few versions after that. I haven't tested it in 139.

Thank you so much, Alice!

Note that bug 1959644 is also related to bug 1966737.

Comment 6

[Emilio Cobos Álvarez [:emilio]]

How is this dialog open? In general it is expected that the page under the modal dialog is not repainted.

Comment 7

[Francesco]

It's opened modal:

There are a few cases where modal dialogs prevent the main window from being updated. When/why did this paradigm change?

In fact, sometimes the window underneath the modal dialog is repainted, see bug 1966737 comment 0.

Attachment: Bug 1971121 - Open spell checker as dependent, not modal dialog. r=#thunderbird-reviewers

After bug 1959644, modal dialogs are unable to refresh their opening windows.
Opening the dialog as dependent and freezing the compose window for user
interaction may be a suitable workaround.

This re-enables immediate highlighting or replacing of misspelled words in the
editor.

possible regression? see bug 1974125

Please nominate for beta 141 uplift

Please nominate for beta 141 uplift

Please note the regression this caused, bug 1974125. Quite a bad one since people may rely on "spell check before send" and the message just gets send.

We should wait for the regression fix.

We should wait for the regression fix.

Ideally both are needed of course.

Bt we don't want this bug on esr140 and it ships on Monday so time is very short. If we can only get one into esr140 then I think we should do so.

ALso, because of the release funk/fun of the past week, we have not yet build release 140. BETA 141 is hopefully happening today. RELEASE 140 comes next - exact timing uncertain but I don't see us shipping on Friday or before, so there is actually opportunity to take this on release 140.

Corey will try to coordinate.

Hartmut or others, can you add a beta and 140esr uplift request for this?
