Documentation pop-ups show even when the mouse is not over a typename

When using a coding style where function definitions look like this:

QTime
getTime()
{
    // ...
}

That is, the return type is on its own line, then Creator will show a doc pop-up even if the mouse cursor is not currently hovering over the "QTime" string in the editor. Instead, it shows it when the mouse is anywhere on the same line as the typename. Visualizing this in ASCII:

QTime                                     -> M <-

If you place the mouse where the "M" is above, you get a pop-up. The result of this is that with that particular coding style, the chances of getting a pop-up when you don't actually want one are pretty high. Very often I park the mouse somewhere out of the way and want to start typing, and a distracting pop-up shows up. Of course one can ignore it since it goes away after a while if you continue typing, but a mouse is usually very close to the keyboard and typing on it very often results in micro-movements of the mouse, which trigger the pop-up again.

It is only a minor annoyance, but still, it looks like a bug.
