Combine Text + Rectangle Layers then Align

2 comps joined, when 2 cubes layers are combined, then their combined anchor set to top left, and you top-align the combined layer to the window top for example, it works.

If you do the same with a cube + text layer, there is an offset from the window top.
Maybe it's me doing something wrong and obviously missing something, or the text layer height is bigger ? But with such small text I doubt it ?

Thanks
