Describe the bug

This is related to #4912

In generated source map, you have two sources but only one sourceContents. this is not an issue on firefox windows but is a serious issue on chrome windows


and will screw up the debugger

And not only vue, you see there is inconsistency between file to file in react to

one file starts with C:, and the other start with c:, this will not cause an issue because

you got one two one match between sources and sourcesContent in the sourcemap

how to fix: don't mix up uppercase and lowercase Driver letter in sources, and don't add both of them to the sources, be sure to match up sources length with sourcesContent
