User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:71.0) Gecko/20100101 Firefox/71.0
Steps to reproduce:
- Load a Webpack-powered website with ~60 JavaScript bundles (that are source-mapped to ~4000 files)
- Open all the 60 bundles as tabs in the Debugger
- Close the website
- Open the website in a new tab (with devtools closed)
- Wait for the website to finish loading
- Open the devtools
Actual results:
The debugger hangs for 20-25 seconds.
Expected results:
The debugger should be snappier.
