Bounding Box bug
Adobe, have you seen this page. https://forums.adobe.com/thread/1148039
The bounding box problem has persisted over versions, years. Extremely strange that it continues to pester even to this day. Will you ever do anything about it?

That following thread was created in 2013. After many years, the "correct solution" was highlighted green, does not solve this ongoing issue.
While this may be difficult to recreate under different circumstances, Adobe should at least look into any stray bug cleanups as they continue to evolve.
This is extremely annoying, especially for me, who don't use bounding box and therefore can't see when something else gets selected until I try to transform selection. I have to watch dimensions carefully and undo a lot sometimes.
