The code editor is helpful enough to know that it can collapse (hide) code blocks, e.g. a Python class
or if
block. It indicates this by displaying a little arrow in the column that shows the line numbers.
If I click on the arrow to collapse a region of code, when I then save the file, the editor automatically expands all of the collapsed regions. This is quite annoying especially when working on a small screen. Is this a known bug or issue?
