Ranges: node.start > node.end, but loc still valid

[turdwaster]

Test input:

export default class ParamList extends Vue { // Newline here to trigger
@Watch('deepStuff') private onDeepChange() {} } 

Expected result: all nodes have .start < .end
Actual result: some nodes have a very low number as end, < start

Is this the culprit? Was expecting something along the lines of node.end = endLoc.index?

Line 402 in 8956dc5

node.end = endLoc.column
