Element Hider can't select anything on Wolfram Alpha

[spaghetti2514]

Attempting to use the element hider on a Wolfram Alpha results page darkens the page, but hovering over anything does not highlight it and clicking does nothing

The following error is printed to the console when the element hider is activated:
Error: Invalid value for <path> attribute d="" [element-picker.js:313]
Using master pulled minutes before making this bug report

This is possibly a duplicate of #99, but behavior seems different

Can you give me a specific URL?

I need to set explicitly pointer-events on the <svg> element, the web page sets pointer-events to none in its own CSS.

The error message Error: Invalid value ... is benign, it's actually an open issue in Chromium somewhere, an empty path is a valid path.
