After the last update, a problem arose: when editing Python code, after one indent (Tab) and a line break (Enter), a dash (-) appears at the beginning of a new line, which must be deleted manually.
The problem is solved either by erasing the dash or using the key combination Shift + Enter.
I assume that the problem is related to the fact that the code blocks began to be perceived as plain text, and it became possible to create bulleted lists, which is not the expected behavior.
