ButtonGroup inside Label hover state styling bug

Environment

• Package version(s): core v4.3.0
• Operating System: macOS
• Browser name and version: Chrome

Code Sandbox

https://codesandbox.io/s/blueprint-sandbox-forked-ge4jfc?file=/src/CoreExample.tsx

Steps to reproduce

1. Hover over label text

Actual behavior

First button in group styling changes to hover state. This is confusing because the first button continues to appear hovered even when a user hovers over one of the other buttons -- this makes it ambiguous what may be selected or clicked on "mousedown".

Expected behavior

No button hover styling when hovering over the label text. When hovering over one of the buttons, only that one should get hover styling.
