1773360 - Pressing `Enter` after adding a recipient to a mailing list fails to move focus to the next recipient input slot, and no empty slot with focus after `Edit list`

Status: RESOLVED WORKSFORME

(Thunderbird :: Address Book, defect, P3)

Description

[Thomas D. (:thomas8)]

Attachment: Screenshot 1: No empty row after `Edit list`, and `Enter` won't move focus to the hidden new row it creates

Seen on Win10.
Works in beta 102.0b3 (64-bit).
Regressed in daily 103.0a1 (2022-06-08) (64-bit) - let's make sure we know the cause so that this won't spill over into beta. Alice, could you find the regression range?

STR

1. From Address Book, do New List (not keyboard accessible, Bug 1751282)
2. Add a recipient in first input slot, e.g. Jane <[e-mail]>, then press Enter
3. Close dialog and edit the list again (hint: only possible via Properties context menu of the list in directory pane, if you don't know where that lives or how it's called, tough luck for you!)

Actual result

• after step 2: when pressing Enter after adding a recipient, a new empty input row gets created, but the focus won't move there unless you press Tab. Not practical.
• after step 3: when opening an existing mailing list for editing, it won't even show a single empty slot until you tab through all existing recipients (which might be 100 or more), and then press Enter exactly on the last one (which creates the new row, and then you need to press Tab again to focus that). Perfect recipe for support outcries: "Cannot add more recipients to my mailing list..."

Expected result

• after step 2: as in TB 91, pressing Enter after adding recipient should create a new input row and focus that.
• after step 3: as in TB 91, after Edit list of existing list, empty row should be shown at the end of the list and have focus.

I cannot reproduce the problem.
It works as expected in Daily 103.0a1(20220608094750) Windows10 64bit.

This was reproducing reliably when I filed it, but no more.
Wfm in 103.0a1 (2022-06-13) (64-bit), Win10.
