MacOS Tahoe 26.2 seems to have made Thunderbird more inclined to trigger the window-focus bug

There's a well known "window-focus bug" in MacOS 26, where clicking on a window (even the title bar) doesn’t bring that app to the front. It seems like Thunderbird is particularly susceptible to this bug, and I was kind of tolerating it in 26.1. But just today I updated to 26.2, and oddly this has made the problem worse. Is anybody else seeing this and is anybody aware of a fix? Various MacOS discussion groups recommend tweaking MacOS mission control settings, but I don't use mission control at all.
