Type the following text in the Rich Text Editor (there is a line break after the first line):
This is heading #3
This is the next line. It is in paragraph format.
Format the 1st line as "Heading #3". The 2nd line remains in paragraph format
Now switch to the Plain Text Editor
The above text becomes (line break is missing):
This is heading #3This is the next line. It is in paragraph format
Switch back to the Rich Text Editor and all the text is in Heading #3 format.
The above behavior is reproducible when the first line is in Heading #3 format and the second is in paragraph format. This does not occur when both lines are in the same format (H3 or paragraph). Is this a bug of some sort?
