"Share" tab broken

[dbartholomae]

When I click on the "share" tab in a timer, the timer doesn't react to any more clicks, and even reloading the page doesn't help. I'm on Google Chrome. You should be able to reproduce by just creating a new timer and clicking on "Share".

Here's the error showing up in the console:

Uncaught TypeError: Cannot read properties of null (reading 'src')
