This reverts commit 9f0f5d1ab1.
Commit cb87d03fe9 made the preview_*
variables const and non-reactive likely by accident, which resulted in
build errors and the examples no longer interactive.
This makes the preview variables reactive, allowing the examples to be
interactive once again.
Changelog: Fixed
Mfm cheat sheet was using constants in v-model.
I additionally set the textareas to readonly because now the
examples don't pretend to be interactive anymore.
* chore: fix some lints automatically
Fixed lints that were automatically fixable with `eslint --fix`.
* fix type
* workaround for empty interface lint
