Pressing the “down key” in the python notebook causes an error (or warning - i am not sure) to popup that reads “Cannot read properties of undefined (reading ‘fontSize’)”.
Steps to Reproduce
Open a python notebook.
In a cell, type something, multi-line. When you use the arrow keys to go “up” and “down” with the (text) cursor, if you go down and read the last row of the cell, the effect is triggered.
Same happens if you are in so-called “command mode”.
Expected Behavior
If you reach the bottom of the cell and you keep pressing down, the text cursor should go to the next cell bellow that (if it exists; if not, nothing you are at the bottom).
Same issue here — pressing ↓ in .ipynb cells throws ‘Cannot read properties of undefined (reading fontSize)’ and I can’t switch cells unless I press ESC. I’m using Cursor version 1.2.1 on macOS.
Exactly the same thing for me. Same error message pops up also when I press the arrow key upwards at the first row of the cell, but in that case the cursor moves to the above cell. The same error message also pops up, when I run a cell with shift+enter or enter into a cell with enter.
