Account settings menu displaying under emails
I'm not sure if someone has brought this to your attention yet, but while I have the "Dark Theme" applied, the accounts menu displays underneath emails (see screenshot).
When I disable it shows correctly. I'm not sure if this happens with other themes.

it was a bit tricky to solve.
I had both themes checkmarked and the menu still popped down under the email list.
After going through the effort of creating a screenshot and text describing the problem, I found this thread. After deselecting the checkmark for the original, "Dark" theme, the menu now pops down, dark, and on top of the email list
I guess I did not know how to make a new theme selection active(uncheck other themes? or restart?). I am not sure why I might want more than one theme checked at a time.
