Typing (or pasting) html in to a chunk or snippet won’t allow me to save the chunk or snippet. ie: <test><test2> will fail because of the ><. If I have a character between the >< like so: >a<, then it will save fine. This of course won’t work out because it will show those characters on the page.
What happens when I actually try to save is the little save progress meter will pop up briefly but there will be no save message in the upper right and the contents do not actually get saved.
