I should be able to type e.g. < div > without any spaces in the editor, and it should properly escape it (i.e. "& lt ;div& gt ;" w/o spaces) such that it displays in my post as plain text.
At the moment, they seem to be silently stripped and are nowhere to be found in the output source.
Edit: Apparently when I type "& l t ;" into the editor without spaces, it shows up as "<". Again, this should be escaped so that I can type ampersands without them being evaluated as HTML entities.
Edit 2: Furthermore, when I edit this post, "& l t ;" (w/o spaces) gets evaluated to "<" and that's what shows up in the editor. When I edit a post, I expect to see the exact same text that I entered into the editor when I originally posted.
I know these are basically all the same bug, I'm just trying to be explicit to help the developer fix and verify the behavior.
