Canvas color changes while popup/pulldown menus are open

[jmatth]

Description

Using MacosPulldownButton or MacosPopupButton causes the background of the example app to change to a different shade of grey while the popup/pulldown is open. This happens in both light and dark mode but is more noticable in dark mode.

Steps To Reproduce

1. Run the example app
2. On the first page open the pulldown buttons under the MacosPulldownButton section
3. On the same page open the popup buttons under the MacosPopupButton section

Code sample omitted as it is present in the example app of the repo.

Expected behavior

The popup and pulldown buttons open without affecting other elements on the screen.

Actual behavior

The entire background changes to darker shade of grey while the menus are open.

@jmatth Does this issue persist in the 2.0 beta?

[jmatth]

@GroovinChip Yes, I just ran the example on 044af12 and it still displays this behavior.

[GroovinChip]

Ok, I'll look into it
