The new update of Google Chrome cause a glitch in the course edit page.

Hello,
I think the new update of Google Chrome cause a glitch in the course edit page. It happens when you open more than tab of the course settings or with a long content in your course page, an overlapping occurs like the screen shot:

Chrome version 77.0.3865.75 (Official Build) (64-bit).
The overlapping issue doesn't present in Firefox browser.

@SaeedMasri This isn't actually a bug in LifterLMS, it's a bug in Chrome (from what I can find).

Here's the Chrome bugs:

https://bugs.chromium.org/p/chromium/issues/detail?id=1003556
https://bugs.chromium.org/p/chromium/issues/detail?id=1002969

And he's the issue in the Gutenberg project: WordPress/gutenberg#17406

There's a potential workaround with a bit of PHP / CSS that could solve this for you immediately.

I'm not going to attempt to resolve this within LifterLMS but thanks for bringing it to my attention.

@SaeedMasri it looks like this is actually already fixed with the Gutenberg plugin. You can install the latest plugin to fix as a holdover to what I imagine will be included in a future WP release. It looks like the Chrome bugs are already fixed on Chrome 78 (dev) and slated for release on Oct 22

I'm using Firefox until then, thanks!
