LESS: Parsing error with contiguous ampersands (&)

[parkerbossier]

Input

.Thing {
	&-left {
		color: red;
	}

	&-left&-otherLeft {
		color: blue;
	}
}

Output

Parsing error: myfile.less
Please check validity of the block starting from line #6
CSScomb Core version: 4.2.0

4 | 	}
6*| 	&-left&-otherLeft {
7 | 		color: blue;
8 | 	}

Syntax: less
Gonzales PE version: 3.4.7

Note

Adding a space between &-left and &-otherLeft in the &-left&-otherLeft line works (but is obviously a different selector).
