Performance issues when using the scrollwheel if the <tr> has a bottom border

[robclancy]

Weird issue. I can't reproduce on the docs examples but just making this issue incase there is something that you think of that is causing this. I do extend some things but reverted them and just did a CSS border (I extend for classes) and it happens still.
Super confused, will just move the borders to the cells.

Had same issue on the cells. But if I do a full border instead of just the bottom it is fine (and collapses anyway so looks the same).

@robclancy Thanks for the report — can you explain a bit more about what you mean by performance issues? Are the cells failing to render altogether, or does the table have some jank while you scroll, or maybe something else?

Jank while scrolling. Jitters when trying to scroll fast with the wheel. If I scroll slow it doesn't really happen. I have had to sideline implementing ember-table because I have no time to look more into it now.
