A single newline isn't being treated as a separater

Describe the bug
In Plain edit mode, a single newline isn't being treated as a separater similar to spaces which is breaking bold and italics rendering and possibly other formatting. Separating formatting by a space or two newlines still works. Also, this problem isn't occuring on the web version of Notes or the latest Apple store version of Nextcloud Notes. In the screenshot the top set shows the problem, the second set shows putting a space at the front of each line works okay, and the third set shows a double newline working okay.

To Reproduce
Steps to reproduce the behavior:

1. Start a new note
2. Type the following:
   one
   two
   three

Expected behavior
one, two, and three should all be bold, but only one is

Stacktrace
(not applicable)

Start by reproducing the issue in the Android app's Plain edit mode with the three lines shown in the report. Trace the formatting/rendering path to see how a single newline is handled, then compare it with a space and a double newline. Done means all three lines render bold, matching the expected behavior and the web and Apple versions.
