I'm trying to figure out why CSSBaseline of Material UI is breaking the background color alignment of React-mentions and how to solve this (https://www.npmjs.com/package/react-mentions)
Take a look at the following setup: https://codesandbox.io/s/frosty-wildflower-21wqm
Currently I'm pretty much stuck and I really hope someone can help me to find the fix.
Please let me know if there are any questions.
Cheers
