Describe the bug

If you click a flyout button on mobile, it gets highlighted, and then never gets unhighlighted.

To Reproduce

Steps to reproduce the behavior:

1. Open the playground on mobile
2. Add a variable using the "create variable" button in the variable flyout.
3. Observe how the button stays highlighted even after you've used it.

Expected behavior

The button should lose its highlight.

Additional context

Usually the button loses its highlight when you stop hovering, but there's no hover on mobile.
