"cheap-module-source-map" is the default source-map generation mode used in created-react-dev mode because of speed. The major trade-off is that the source maps generated don't contain column numbers, so DevTools needs to be more lenient when matching AST nodes in this mode.
In this case, it can ignore column numbers and match nodes using line numbers only– so long as only a single node matches. If more than one match is found, treat it the same as if none were found, and fall back to no name.
* Add named hooks test case built with Rollup
* Fix prepareStackTrace unpatching, remove sourceURL
* Prettier
* Resolve source map URL/path relative to the script
* Add failing tests for multi-module bundle
* Parse hook names from multiple modules in a bundle
* Create a HookSourceData per location key (file, line, column).
* Cache the source map per runtime URL ( = file part of location key).
* Don't store sourceMapContents - only store a consumer instance.
* Look up original source URLs in the source map correctly.
* Cache the code + AST per original URL.
* Fix off-by-one column number lookup.
* Some naming and typing tweaks related to the above.
* Stop storing the consumer outside the with() callback, which is a bug.
* Lint fix for 8d8dd25
* Added devDependencies to react-devtools-extensions package.json
* Added some debug logging and TODO comments
* Added additional DEBUG logging to hook names cache
