It is not possible to tab to the edit box that contains information about the currently running version of LibreOffice. This makes it difficult for keyboard only users to copy and paste this information.
Steps to Reproduce:
1. Go to the help menu
2. Select About
3. Tab through the controls.
Focus did not land in the edit box.
Tab should have placed focus in this edit box.

I move it to enhancement because it's not strictly a broken feature, just something not practical with keyboard.
