I am using Thunderbird on a Fedora machine. My desktop manager is Gnome. After the last update the version number for Thunderbird is 78.3.1
After installing Thunderbird (during setup from Fedora 32), two items were added to the Gnome application menu:
'Thunderbird' and 'Thunderbird on Wayland'.
The normal way to use 'Search' is by selecting Edit => Search and than a submenu should display.
When using 'Thunderbird', the submenu displays as usual..
When using 'Thunderbird on Wayland' (which is my default) the submenu is not displayed.
I first posted a message on mozillazine.org (http://forums.mozillazine.org/viewtopic.php?f=31&t=3066324&sid=fcc99b05a4a44972f1fecead04049eca).
According to mozilla.org, this problem is Fedora related and should be filed here.
Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. Open Thinderbird
2. Select Edit -> Search
Actual results: no results
Expected results: submenu
