- Updated code content to get specific text selection instead of using
node-based handling which could return the whole document when
multiple top-level nodes were in selection.
- Simplified how code gets applied into the page to not be node based
but use native editor methods to replace the selection. Allows
creation from half-way through a block.
Tested on chrome+Firefox on Fedora 35.
Builds upon changes in #3246.
For #3200.
