To all problem repoters:
Which is actual problem of this bug? Or which is actual request?
(A) Because "trash selection UI" accepts other tha [Gmail]/Trash as "trash folder in Tb for Gmail IMAP aaccount",
Tb must respect the user's trash folder choice by user, even if this is Gmail account.
Tb users know Gmail's particularity pretty well.
i.e. UX bug.
(B) "Always Use [Gmail]/Trash (localized name by Gmail if Display Language in Gmail is not English)" is reasonable and aacceptable.
"trash selection UI" must not accept trash folder selection change if Gmail IMAP.
"trash selection UI" must not lie on actual trash folder selection.
i.e. UI bug.
Root cause of confusions by users in this bug is "mismatch between UX and UI".
Second cause is that Tb users usually never try to read "User's Guide or Manual of Gmail/Gmail IMAP provided by Gmail", even though "particularity of Gmail/Gmail IMAP" surely exists. Who is responsible to the "particularity of Gmail/Gmail IMAP" is never Thunderbird Developers. Who is responsible is surely Gmail/Google. Gmail's recommendation is "Remove it immediately" because Auto-Expunge of Gmail IMAP is enabled by default.
FYI.
For "Archive granularity", [Gmail]/All Mail is used as Archive folder by default.
So, solution like (B) is already introduced to avoid user's confusions.
"Archive granularity" option is disabled in UI if Gmail IMAP.
