[Bug 2121028] [NEW] Sudden pop-up while writing can cause unintended action

[J B]

Public bug reported:

I set the update-manager to automatically update. Unfortunately it does
this not in the background, but through a pop-up. The pop-up window can
happen anytime, including when I am in the middle of writing a paragraph
in another application. Consequently, the update-manager can receive a
space bar less than a second after it popped up, and thus "steal" key
strokes and take an action before I could notice the new window.

A similar issue occurs on Thunderbird/Firefox when installing add-ons,
and they solved it by disabling the "Install" (or otherwise serious
action button) for the first ~second after the popup appeared.

I would suggest a similar change here, to disable the "OK" and "Install
updates" and "Restart now" buttons for the first 0.5 seconds when the
window is shown.

Ubuntu 24.04.3 LTS
