Fixes #52775 (comment)
Supersedes #53153

before this fix, the lines that were actually executed were calculated using the source file on the disk - this is not the case when using ES loaders/transpilers.
since we don't need the actual code run we create fake lines with a dummy char, just to map the dummy line to its original source
