Source maps for workbench.main.js?

[Xlator]

I am having a go at modifying the appearance of quick-input using the Custom CSS and JS Loader extension, with the goal of making the Command Palette and the excellent Which Key (potentially also the NeoVim console) appear larger - similar to Alfred, Spotlight or some other task launcher. However, this also affects the IntelliSense menus, which I'd like to avoid.

I haven't been able to find the DOM elements of the IntelliSense menus, so I'm wondering if there is a way to get hold of the source maps of the workbench, or some other way to find the event that is fired when IntelliSense pops up, or if anyone just knows the particulars of the DOM element I need to exclude, or a more specific selector for the inputs I want to modify...

Here's my code so far, just CSS (Sass): quick-input-tweak.scss

Thanks for your attention. <3
