Entering HTML macro activates a wiki markup block

The

macro is slightly broken if you enter it using the "just type the curly brackets" method. Eg., if I type {code}, a code block pops up. But if I type {html} I get a wiki markup block with the text string {html} inside.

The workaround is to NOT type the closing } curly bracket but instead you must lift your hand off the keyboard, go for the mouse and select HTML from the pop-up menu.
