Qt Creator changes font size when Cmd is pressed after scrolling has started (Mac OS X)

0. Install Qt Creator on MacBook with glass trackpad running Mac OS X 10.6.6. Exact OS X version is probably not important, glass trackpad may be important (you need to be able to start kinetic scroll by two fingers)

1. Open some QML long document (probably can be reproduced with other file types as well)

2. Start kinetic editor scrolling by two finger swipe (upwards or downwards)

3. While editor is still being scrolled, but you fingers are not on touchpad anymore press Cmd

Actual behavior
4. Font size changes as if you were pressing Cmd and (scrolling on touchpad or pressing +/- repeatidly)

Expected behavior
4. Nothing happens.

Font size change on Cmd+Scrolling is quite handy, but when it happens "on its own" (you released fingers from touchpad already and scrolling action is just "being finalized"), it feels quite annoying
