Window content doesn't refresh if windows are resized via the Accessibility API

[rg-manytricks]

Describe the issue
When using our app Moom to resize UTM windows, window content does not automatically resize to fit. (This will also be true of other apps that resize windows using the Accessibility API.)

It appears to us that your code that does automatic resizing on window size change doesn't run if the window is resized via the Accessibility API, but does run on manual resizing. A customer recorded this video that demonstrates the issue: After resizing with Moom, the content doesn't adapt to the new window size. But as soon as the user manually adjusts the window size after using Moom, the content adapts to the new size.

If UTM implemented windowDidResize in the window's delegate or observed the didResize notification for that window, and then applied the same logic it applies when manually resizing, then the content would automatically scale when Moom (or any other app that resizes via the Accessibility API) is used to resize UTM's windows.

Thank you for addressing this so quickly; we (and other Accessibility API apps) and your users appreciate the support!
