there are 80K generated breakpoint positions in debugger.js using the flush/task strategy can use a lot of resources.
doing one invoke for getOriginalLocations is much cheaper.

Just saw this in my (500 line app code) nextjs/typescript app, where it took 5+sec to load the breakpoints (which doesn't have a loading indicator, so is very opaque): https://perfht.ml/2CdhaEu
