Toast issue in Toolbar

[corywatilo]

After saving actions, it looks like a toast notification shows up, but it's hard to read. And sometimes doesn't ever go away.

Repro

Define a couple actions in a row using the Inspect tool

current theory: css variables assigned to :root are not available to the toolbar in its shadow root

[pauldambra]

Hmmm.. toolbar.css opens

@charset "UTF-8";:root {
    --toastify-color-light: #fff;
    --toastify-color-dark: #121212;

the missing new line might be the fault there

[pauldambra]

built CSS for toolbar declares root variables twice... once from /* node_modules/react-toastify/dist/ReactToastify.css */ and once from /* frontend/src/styles/global.scss */
