It's a small issue, but an issue nonetheless.
1) Go to a project with branches.
2) When you mouse over a branch, it changes color to let you know which branch you are over.
3) When you click the three dots that signify "more options," the branch stays highlighted at first. But when you move your mouse down to select one of the options, the table-row un-highlights.
That's a problem because, when you go down to "close branch", it can be a little difficult to know which branch you're closing.
