Best Practices Checklist

We're trying to move away from some deprecated patterns in this codebase. Please
check if your PR meets these recommendations before asking for a review:

• Any new files are using TypeScript (.ts, .tsx).
• Avoid propTypes and defaultProps in any new or modified code.
• Tests should use the helpers in src/testUtils.tsx (specifically initializeMocks)
• Do not add new fields to the Redux state/store. Use React Context to share state among multiple components.
• Use React Query to load data from REST APIs. See any apiHooks.ts in this repo for examples.
• All new i18n messages in messages.ts files have a description for translators to use.
• Avoid using ../ in import paths. To import from parent folders, use @src, e.g. import { initializeMocks } from '@src/testUtils'; instead of from '../../../../testUtils'

@rpenido Looks good. Just have one problem, the tiny-mce-editor doesn't seem to expand to take up the full space in fullscreen. I don't think it is a very simple problem as there is no clear option to dynamically resize the editor.

I don't think it is a very simple problem as there is no clear option to dynamically resize the editor.

I tried to fix it, but the problem is that the tiny-mce-editor sets the editor css property 'height', even if we only set the 'min_height`. I didn't find a way to fix it.

@rpenido It's missing a padding between the buttons
