Regression: Sidebar on larger (e.g. iPad-like) touch capable devices

[aeharding]

Describe the current behavior

At some point, the functionality depicted in the video from the following PR stopped working:

#3088

Now, when the sidebar is open, the content dissappears and scrolling is broken/weird (see video):

Kapture.2023-02-15.mp4

Steps to reproduce

1. Use an iPad or a browser inspector with touch enabled (e.g. iPad in Firefox Inspector)
2. Go to PeerTube (nightly and/or stable), open sidebar
3. Observe content disappears and scrolling is weird

Describe the expected behavior

• Content should have a black transparent overlay
• Only scrolling sidebar should work.

Additional information

• PeerTube instance: https://peertube2.cpy.re/
• Browser: iOS iPad or iOS iPad simulator in FireFox (e.g., touch-enabled large screen device)
