After initial release on test wikis it has been confirmed that the initial dark styling of bracket matching makes it hard to see the cursor and can be distracting.
In combination with color changes being done in T271895: Update CodeMirror syntax highlighting color scheme to meet accessibility standards, the styling will be made more subtle.
- CSS should match the below:
color: inherit; box-shadow: inset 0 0 1px 1px #999; background: #eee; font-weight: bold;
- Confirm that 'inherit' is working and the color of the bracket remains the same when highlighted
