the code infrastructure is there for .eml export since https://github.com/thunderbird/thunderbird-android/issues/9937 - but atm needs a debug build and feature flag set to be accessible
fyi, there exists a bugzilla entry on this at https://bugzilla.mozilla.org/show_bug.cgi?id=1939280 - linking a similar solution as the parent post (.editBMPanel_locationRow)
on some web-based map tools (osm.org being a popular one), there's no scroll event to hide the now bigger toolbar. This is an issue on small screens (5").
