Not really.  This is 'redisplay-highlight-region-function' at work and
it's by design.  The idea is that when the region starts or ends
within an overlay, it is shown within that overlay.  If the region
covers the overlay completely, it is not shown within that overlay.

The effect is slightly different for GUIs and TTYs.  On TTYs only
'widget-field' is affected here, on GUIs 'custom-button' as well.
Which is probably by design too but I don't know why.
