Gitlab markdown: spaces at end of line sometimes inserts a period


#1

When I use gitlab markdown, e.g. in a wiki, I want to be able to start a new line of text.
My understanding is that two or more spaces at the end of a line = a new line when published.
However, sometimes gitlab inserts a period when I type the two spaces!
Which is a real pain, because I have to go back and delete the period, then make sure there are at least two spaces, in order for the next line of text to be on a new line when published.
Why does gitlab pseudo randomly insert a period when I type two spaces at the end of a line?
How do I make it stop doing this?
My current work around is to make my text code inside triple back ticks, which is way less than ideal.
