The height of table cells with a cell next to them having rowspan>1 are not computed as expected. For example, on the reference page, "Red (Category III)" and "Red (Category II)" are too thin while "Red (Category I)" is too thick. Their heights should be the same.

Created attachment 461610 [details] Safari 15.6 differs from other browsers I am able to reproduce this by taking Wayback Archive link - it does not have CSS or JS but it does show table layout being broke as highlighted in the screenshot. Link - https://web.archive.org/web/20090207135953/http://pacificstorms.org:80/template.php/alert-system I am going to change it to "New" so others can have a look. Thanks!

This breaks the current website http://www.infiniteloopfilms.com/tmb.html where the menu bar has a jump at the very beginning.
