Description

With WP 6.0 beta 1.
A locked reusable block (with "restrict editing") text content is still editable.
From my tests, it's happening only for blocks containing text (paragraph and list block for example).
(See video for example).

Step-by-step reproduction instructions

1. Insert a paragraph or list block, enter some text
2. Add it to reusable blocks
3. Lock it (with "restrict editing" option)
4. Click on the text, I can edit it
