Hover over the text inputs in the attached test case. In Safari 5.0.4 and FF4.0.1, the boxes turn red on mouse over and blue on mouse out. In the nightlies, the plain text input doesn't change color at all and the speech input changes when the mouse is hovered over the microphone, but it never changes back.
This was observed on Linux and Mac Chrome 12.0.742.9 (WebKit r84325). It doesn't reproduce on Chrome 11.0.696.57 (WebKit r80534). I haven't tested on Windows or in Safari nightly.
Safari on Mac seems to be unaffected.
I confirmed that this issue was reproducible with Chrome 12.0.742.12, but I couldn't reproduce with Chromium 13.0.751.0. So, It seems WebKit already has a fix.
This issue looks an issue of event handling. Dimitri, do you have any idea?
