This has been reported before both here and in Issues.
While we wait for a fix, I made a work around. A made a new control out of a container, a segment button, and a rectangle. When the control is disabled the rectangle is visible (but it’s not seen by the user because it’s transparent). Clicking or hovering has no effect the the segment button behind. When enabled, the rectangle is made invisible and but button works as advertised.
Hope this helps someone.
