`Add modifier` -> `Text` works differently when right clicking on object or in parts list

[ulab]

Description of the bug

Adding a text modifier does not work by right clicking on a part on the sheet in 3D editor view.

Project file & How to reproduce

Right click on a part on the sheet in 3D editor view and select Add Modifier -> Text. This just adds a new text part on the bed.

Right click on a part in the parts list and select Add Modifier-> Text. This correctly adds a text modifier to the part which can be attached to a surface of the part.

Interestingly enough it did not happen when I just added a basic Box shape as part

The STL file I wanted to add text to: Gridfinity E3D Revo Nozzle Holder 1x2x3(1).stl.zip

Your model is broken. You have to fix it. https://help.prusa3d.com/article/corrupted-3d-models-for-printing_2205

1. The model was not reported as broken by PrusaSlicer.
2. This does not explain why it works using the sidebar, but not directly clicking on the model?
3. Aspose's repair tool reports "Some parts have reversed normals". After conversion, PrusaSlicer reports it as broken and auto-repairs 2359 errors. The issue stays the same.
4. Formware's STL repair reports "447 Non-manifold edges, 721 Inverted faces and 324 Duplicate faces", the repaired file works as expected.

I still think this is an issue, because PrusaSlicer did not report it as broken and it "kind of" worked one way, but not the other. This will confuse users.

ad1) Sorry, fast detection of broken model is not detecting 100% of issues. ad2) Ray Casting did not work on your model.

Fix after your comment: I changed fail recovery behavior to create part (similar as right panel) instead of creation new object, when model is not hitted by ray caster.

Still, dragging text over surface will not work til you repair the model.
