I’m on Anki Desktop Version 23.12 (55ef11af). Windows 11.
I edit cards in the browser or in the “add card” window.
When moving the cursor with the arrow keys, the cursor will enter into inline MathJax equations just fine, but NOT in block equations. (It just passes over them.) To edit block equations, I have to click on the equation with the mouse.
This bug persists with all addons disabled.
