Reduced testcase
Verified in Safari 9.0.2 (11601.3.9) and WebKit Nightly 11601.3.9, r194284
In some circumstances, changing the font-size on a display: table-cell element makes said element change its position. The added space behaves like padding and lights up green in the inspector but is not removable by setting style.paddingTop = 0 on the node.
Note that this behaviour can only be observed when two display: table-cell are used, it’s not present with only one such element.
Firefox and Chrome do not exhibit this behaviour.
STEPS TO REPRODUCE
1. Open the attached testcase in Safari or a WebKit nightly
2. Hover over and out from the texts a few times
EXPECTED RESULTS
When not hovered the text should look the same as when the page was loaded.
ACTUAL RESULTS
The position of the text changes with each hover.</pre>
