Bug 1991431 - [devtools] Migrate the HTML Editor to CM6 r=devtools-reviewers,nchevobbe
Highlights of this patch
- Updates the codemirror 6 bundle
- Restructured the `setText` api to have an options object
- Added a new `saveToHistory` option to handle not add to history (when set true), when re setting
the editor content. This is used to replace `clearHistory` behaviour in cm5.
- uses `config.keyMap` for setting the cm6 key maps
- Stop propagating `keydown` event to avoid the hijack when pressing the backspace key by the markup component
- Small cleanup on the usage of compartments
- Remove the extra `undo` intermediate change needed for cm5
