Oh for sure! Not trying to get on your back, just agreeing from a UI developers pov :) I seem to have misunderstood your original intent but we're saying the same stuff I think

I do often desire a "click to continue" option, especially helpful for asynchronous tasks. Start a render, and when you get back it says 100% without you having to look at the output folder, for instance. I get what you mean though, it certainly should say 100% unless it's totally donezo. Probably lazy rounding errors in some cases (Microsoft products are the worst at showing accurate progress bars)
I've had issues like this (but with Bluetooth) resolved by unplugging the computer from the wall, and holding the power button for a few seconds to clear out the capacitors.
If it's a laptop that's a bit harder to do, but might be worth a consider.
I haven't gone so far as to figure out why this fix works, but it's happened a few times now and i can't deny results
