The questions is: does current-column, move-to-column, etc. on master
indeed report the column number and move to the place whose column
number _on_display_ is as you ask them?  If they do, then this is the
correct behavior, and features that expect something else should
adapt.  But if move-to-column moves to a column that is visually
incorrect, I'd still like a simple reproducer.  Even if one must use
company-mode and eglot, can you post a recipe that doesn't involve
their installation via package.el?  Suppose I download the relevant
*.el files to my system and manually load them as needed, can you show
a recipe that loads whatever is needed and then reproduces the issue?
