Cannot resize lists on mobile

[50-scratch-tabs]

Expected Behavior

Please describe what should happen

If you zoom in enough, even on a touchscreen, you should be able to use the little equals sign to resize lists.

Actual Behavior

Describe what actually happens

On touchscreens, you cannot resize lists, regardless.

Steps to Reproduce

Explain what someone needs to do in order to see what's described in Actual behavior above

Steps to reproduce the behavior:

1. Go to 'https://scratch.mit.edu/projects/editor' on a mobile device such as a phone.
2. Create a new list
3. Zoom in on the equal sign that you use to resize the list
4. No matter how much you try, you cannot resize the list.

System Details

If the problem occurs in the browser, please provide operating system and browser e.g. Mac OS 10.11.6 Safari 10.0

If using one of the Apps please provide the app version and device details, e.g. Scratch 3.0.57, Android 9 on HP x360 Chromebook

Android 14 (I think), Firefox for Android
(But this should be reproducible on almost any touchscreen)

Screenshots
If applicable, add screenshots to help explain your problem.

Not really easy to explain with screenshots.

Also, @BigNate469 has come up with a fix and posted it on that forum topic, and I plan to make a pull request fixing it. (The pull request template asked what issue it fixed so I figured I should make one)
