Digging deeper into bug 43587, it seems to be related to move-to-column behaving slightly different when the text in a line has the invisible property set.

Here is how to recreate. According to the documentation for move-to-column, I would not expect any difference between the two lines:

> Optional second argument FORCE non-nil means if COLUMN is in the middle of a tab character, change it to spaces.

For the first line, the tab has not been changed to spaces...

Am I overlooking something?

Kind Regards,
Christoph
