Thank you for filing this report.
In your screenshot, I can see that the Toggle Mask and Layer Path visibility button at the bottom of the Composition panel is disabled. This usually indicates that the View > Show Layer Controls option is disabled. (Though the layer controls can be customized via View > View Options.)
If you enable one or both of those options, does the bounding box return?
