Spinner causes row to grow in height
|Reported by:||nacin||Owned by:||lessbloat|
When replying to a comment, the spinner that gets shown briefly is a bit taller than the row (when you add in padding, line height, etc), causing the row to grow by a pixel or two. It then shrinks again when the spinner is hidden. Related to switching from visibility: visible/hidden to display: none in #21456.
