When I am creating a notebook in the UI editor on DataBricks, markdown cells do not always render after I run them. They still appear in 'editing mode'. See the screenshot below, it should have rendered a H1.

Again, this behavior is not consistent. Sometimes it works, sometimes it doesn't. Refreshing the browser (Microsoft Edge) did render the cell, but I shouldn't have to do this. Please see if this inconsistent behavior can be corrected.
