2020.12-RC3 - Quit with unsaved changes - Save-all doesn't quit

[MichaelAtOz]

2019.05 File/Quit with unsaved edits, dialogue box 'The document has been modified. Do you want to save your changes?', click Save, saves file and quits.

2020.12-RC3, 'Some of the tabs are modified. All unsaved changes will be lost.', click Save-All, saves (shown in console), but does not quit.
Discard does quit.

This is a matter of taste, but...
'Some of the tabs are modified.', sounds a bit odd, 'Some tabs have been modified.' or better 'Some tabs have unsaved changes.' maybe??
