Add quick link in gmail does not work

[tetrode]

gmail has a feature called quick links:

Using chrome, clicking on add quick link works - asks for a title and a new quick link is added
Using brave, nothing happens

Related with #902. Also with #989?

Confirmed this is still an issue; Quick Links is a "Google Lab" feature which you have to enable via Settings in order for it to show up. After enabling, I didn't see any error being logged (I checked both shift+F8 tools and regular F12 tools)
