The figure menu and toolbar are implemented with uimenu and uitoolbar objects and have the same sort of issue.  When they capture a click no other graphics object processes it.

Changing this is likely to be a project.

BTW -- the same happens with gui menu items -- you can try clicking on "grid" button e.g.

I agree that this is incorrect.  The issue is probably that the mouse click is detected and then successfully processed by the pushbutton.  The 'click' is never cascaded to underlying objects which in this case would be the Canvas object for figure 2.  It is that click which updates the current figure property in the root object.

1. Create 2 figures and a button on the second figure
figure; figure;
uicontrol('style', 'pushbutton', 'string', 'text');

2. Select first figure and type
gcf -> 1 (which is as expected)

3. Press button on second figure and type gcf
gcf -> 1 (should be 2)

Note that Matlab correctly assign gcf to the second figure
