Function signature tooltip doesn't update when moving the cursor among function call parameters

Say you have a funtion call `DoSomething(int a, int b, string c)`. Then you try to call it with `DoSomething(a,b,c)`. Normally, in the call, if you put the cursor after "(", then press "Ctrl + Space", you see a tooltip with the function signature. If you use the keyboard to move the cursor to the right, normally, the parameter, where you are at, should be bold in the tooltip. However, this doesn't work. Apparently the signal is broken. What one should do is reactivate the tooltip to get the right part of the signature to be bold.

Irrelevant note: I wanna mention something, and please don't take it the wrong way. While I love Qt and Qt Creator, but recently there have been way too many regression errors on Qt Creator upgrades. Honestly, I don't remember the last time I did an upgrade and didn't have an issue or more. There should be better regression tests to protect against these issues. I want Qt to succeed, but these kinds of errors that happen all the time when I upgrade just demotivate me from upgrading and I'm seriously considering trying alternatives. Thank you very much for the great software, and keep up the great work, and please consider addressing this issue.
