Created attachment 77457 [details] repro case Having a top margin on a contenteditable element makes "enter" insert too much vertical space. See attached test case. Expected: On "enter", the caret moves down by one line height. Actual: On "enter", the caret moves down by one line height plus the top margin.
Works fine in Ff3.6 and Ff4 beta.
All browsers (Safari Technology Preview 159, Chrome Canary 110 and Firefox Nightly 109) are adding similar space (more than line height) after pressing "Enter". Marking this as "RESOLVED CONFIGURATION CHANGED", please reopen if it is issue and something all browsers need to fix. Thanks!
