Steps to replicate the issue (include links if applicable):

• Activate Improved Syntax Highlighting in Beta Features
• Edit a template
• Put cursor into text bounded by opening and closing brackets but not right next to them

(e.g. {{ template text (CURSOR HERE) template text }} )

What happens?:

• Innermost brackets not highlighted

What should have happened instead?:

• Innermost pair of brackets should be highlighted, as they are if the beta feature is disabled

Behavior is extra noticeable with the following CSS applied (no effect if beta feature is on, has effect if disabled):

.cm-mw-matchingbracket {
	background-color: yellow;
	box-shadow: none;
}

.cm-mw-matchingbracket ~ .cm-mw-parserfunction-delimiter {
	background-color: yellow;
}
