It seems that something similar applies to the end text:

The line continues below the text, while I think it should end before. But this also depends on the endTextPlace property, which should probably behave similar to beginTextPlace.
It's difficult to test, because the UI for it is mostly missing in MS4's properties panel.

It would be good to also add a new VTest to this PR, ideally one that verifies all combinations of TextPlace and Alignment, for begin and end text.

It seems that something similar applies to the end text:

Should the end text then also use the 'gap between text and line' property? currently there is no distance added at all

Yes, this makes sense to me. Doubtlessly, the next thing people will ask for is separate controls for begin/continue/end text gap, but that would be a separate feature request.
