New Tag Pane feature seems to have broken autocomplete capitalization of previous tags

Heya, I’m still seeing this issue.

EDIT: as in the Capitalised Tags vs lowercase tag duplicates:
Tags list shows:
#CONTENT
#content
There was discussion about fixes, any progress?

It’s actually broken the use of tags for me in DL, since coming from Workflowy, and I’d really like to use again.

You mentioned above examples like PhD, and how to handle.
IMHO lowercase should be standardised, i.e. ‘phd’ in tag list is correct, as it’s a tag.
Yet in context should have whatever caps u choose, as per Workflowy.
