Describe your changes
Replaced the lookbehind regex in vegaexpr.ts with a normal regex group. Since the resulting matches are anyway re-processed with another regex, the extra capture group in the match shouldn't affect the final result.
Testing performed
Ran python and js tests, confirmed working in jupyter lab in firefox and safari.
New PR after I messed up my repo ;)
