Menu items do not close on second click in Theia 1.62.2

[hasm1k]

Hello,

I recently upgraded my application from Theia 1.46.1 to 1.62.2 and noticed an issue with the top menu bar (File, Edit, View, etc.).

When I click on a menu tab, it opens as expected and shows the dropdown items. However, if I click the same menu tab again, the menu does not close. It only closes if I select an item or click elsewhere in the UI.

This behavior did not occur in Theia 1.46.1 — in that version, clicking the same menu tab again would close it as expected.
Is this a known issue in 1.62.2, and is there a recommended patch or workaround without upgrading to a newer Theia version?

Hi @hasm1k,

This behavior was implemented drive-by during a refactoring.

Personally I agree that closing the top menu again with a second click is the "more expected" behavior. It's also the behavior which occurs when using the Electron native menu.

I'm in favor of restoring the old behavior, i.e. closing the top menu bar again with a second click. Would you like to open an issue for this? If you like you can also contribute the fix.
