Hmmm. I select "line > 2 points" and attempt to draw a line. I see nothing when I move my mouse over the canvas or click.

In a default native install, I get a crosshair and grid dots, and when I select "line > 2 points" I can click on the canvas twice and I get a line between those locations.

Edit: All tools appear to be broken and clicking on the canvas after selecting a tool doesn't draw anything.

I also tried in an incognito tab in case it was an extension or cache issue, still nothing.
