* Modified by the WMDE Technical Wishes Team
* currently based on
* https://github.com/codemirror/CodeMirror/blob/156e6686774c38f1722a8ec5bfc790f7b47fd0e3/addon/edit/matchbrackets.js
* (from 2018-01-26)
*
* Modifications:
* - Introduced findSurroundingBrackets() along with it's `brackets` map. This is called when no
* `match` is found at the current cursor position.
* - Removed the `style` argument from the `scanForBracket` call. This fixes a compatibility issue
* with the "mediawiki" mode that tokenizes some brackets as `[[` or `{{{` pairs or triplets.
