Ever Increasing number of Chrome Console Errors on Profile when editing sidebar

I was investigating a large number of console errors, and found that if you edit the sidebar in the Profile settings, the errors seem to never stop increasing. This screen capture shows what I mean:

I see some errors are related to card_mod even though it shouldn’t be used on this specific page. Either way, the errors attributed to card_mod appear to max out at 35 per edit session (video shows 35, then 70 after I start/stop the edit). The other errors don’t seem to ever stop accumulating.

Can others check whether they see the same issue? I am particularly interested to know if the issue is present or not present with and without card_mod… so in other words, please report back whether you have it installed if you reply stating you have, or don’t have, the same increasing errors.
