Version context button requires rounded left corners

Created by: rrhyne

When the interactive mode is disabled and version contexts are enabled, the version context button does not have rounded corners applied. See the screenshot below:

Additionally, the popover now has a bold blue border where it previously did not. I believe this is the offending style:

[data-reach-listbox-popover]:focus-within { box-shadow: 0 0 4px Highlight; outline: 4px auto -webkit-focus-ring-color; outline-color: -webkit-focus-ring-color; outline-style: auto; outline-width: 4px; }
