Bug [TextMesh Pro] Mesh Bounds Appears to be Incorrect

hi @Stephan_B ,

I have noticed that the mesh bounds can be misreported in some circumstances.

I have been trying to use the Text's reported mesh bounds to assist with layout which led me to double check my results with the in-built info component. Turning on the "Show Mesh Bounds" option in the "TMP_Text Info Debug Tool" component confirms the results I am seeing.

I would expect the orange box to only continue as far as the right hand side of the final t's quad.



If I reduce the Text's RectTransform width, then the mesh bounds begin to display correctly at a certain point:



The same problem occurs with the vertical bounds if top or bottom alignment is selected and the Text's RectTransform height is quite large:



Setup: Unity 2021.3.17 and TMPro 3.0.6.

Thanks a lot.

 

I've also hit an issue where I've managed to break the geometry based centring using Rich Text Tags...

<cspace=-0.1em>25</cspace><size=56%><voffset=0.53em><space=0.035em>%</voffset></size><space=-0.5325em><voffset=-0.013em><size=27%><cspace=-0.3em>OFF</cspace></size></voffset>



It seems to partially linked to the negative character spacing as when I change the final one to 0, it renders more in the centre of the rect (but still not quite centred).

<cspace=-0.1em>25</cspace><size=56%><voffset=0.53em><space=0.035em>%</voffset></size><space=-0.5325em><voffset=-0.013em><size=27%><cspace=0em>OFF</cspace></size></voffset>



Other types of alignment are also broken with the original string, most noticeably Right alignment:
