Minimize shortcut (Alt+M) in comparing dialog is not available in 5.9.2

I'm used to pressing Alt+M when the Synchronization's comparing dialog appears, with new interface it's now a button with "_" glyph. However the keyboard shortcut Alt+M does not work anymore, I have to use mouse to click the icon.

Attached is is the dialog I'm talking about.

It minimizes if I press the button but not with Alt+M.

Thanks.

Thanks for your suggestion.

There is one problem with this now, when I hit the Alt+M during synchronization it minimizes, but when the window is restored the main window (instead of the dialog) is active.

Normally if I hit Minimize during synchronization the dialog is activated as I restore.

Activating a main window causes interesting side effect, I can start adventurous journey through main window which is not normally possible when modal dialog is open.

What does "normally" refers to? Clicking the button as opposite to pressing Alt+M?
