There are so many other ways this can happen that it's really not surprising this happens. Like: started 20 years ago with the UI toolkit in English and a junior dev hence fixed size then suddenly got a growing customerbase in another language and slammed on a translation only to realize it would be a pretty large effort to track down and change each label to resize. Or even just: things adjusting size can simply be a big no depending on software (and you'd use truncation+toltip), because one doesn't want to waste space and/or keeps things aligned so it's easier to learn where everything is. Your browser tabs probably don't adjust size to text, just to name one thing.
