Details

This is an issue found in Rsbuild e2e testing, I'm not sure if it's related to Rspack lazy compilation implementation.

• Playwright 1.42.0 - Lazy compilation works as expected, Rspack rebuilt twice:

start   build started...
ready   built in 0.02 s
start   building src/index.js
ready   built in 0.01 s
start   building src/render.js
ready   built in 0.03 s

• Playwirght 1.43.0 - Lazy compilation not work, all modules are built at first:

start   build started...
ready   built in 0.02 s
