No longer able to spam socket currency on items with Ctrl+LMB

As the title says, I'm unable to use the Ctrl+LMB key bind to spam apply socket currency onto any of my items. This feature was added as a QOL update during the launch of the Necropolis league.

I've tried multiple combinations of keys that include Shift, Alt, and Ctrl. None of them seem to enable this feature. I've also tried having currency both in my inventory and in the stash, that didn't work either.

It's Shift-LMB, but make sure if no software intercepts it.
