Highlight panel blocks click interactions when closed

The in-page checker, when minimized, is a small yellow button at the lower right.

The wrapper around the button in this state is transparent, but is still 400px by 50px div, and is z-indexed in front of the content:

.edac-highlight-panel {
  bottom: 15px !important;
  max-width: 400px !important;
  position: fixed !important;
  right: 15px !important;
  width: 400px !important;
  z-index: 2147483647 !important;
}

To fix: set max-width to equal the button width when the panel has not yet been opened.
