Caused by the align on table rows being incorrectly transformed to float, whereas align on table rows determines content alignment.

This is a bug in our HTML4->HTML5 normalization. Should be easy to fix.

(edit conflict)

When a table row has align=right it's now converted to <tr style="float:
right;">!! which causes this weird display.

This is caused by Gerrit change 13479 -> Anything that are not cells (td, th)
and has align is converted to float, except if it's align=center. It should
have included table rows as well.

This problem surfaces now because of bug 27478

It happens when preview because the switch to HTML5 has been done recently.
When the page cache is refreshed, it will look weird also on page view (unless
HTMLTidy is sanitizing it)

[Importance changed to high]

Working on it with https://gerrit.wikimedia.org/r/24076

The Gerrit change #24076 makes it so <tr align="X"> is converted to use the style="text-align: X;" for TR elements.

New patchset submitted (though for some reason it seems to have picked the cherry picked version on the wmf12 branch.

Pages in squid cache will need to be purged manually. That will self fix whenever an edit is made.
