No cursor in markdown cell in dark mode

Jusf find out this in latest version 1.4.1. There seems to be no cursor in markdown cell when dark mode is on. When dark mode is off cursor is OK. Also in dark mode when editing markdown cell, it’s all “white” with dark text.

Reproduce the issue in version 1.4.1 by opening a markdown cell with dark mode enabled and entering edit mode. Compare the cursor visibility and editor colors with dark mode disabled; done means the cursor is visible and the markdown editor uses the intended dark-mode styling.
