DevTools occasionally freezes when using WASM

elliette commented 1 month ago

I've managed to rather reliably get DevTools to freeze when compliling to WASM.

Steps to repro:

Run devtools with devtools_tool serve --wasm --no-strip-wasm
Enable the WASM setting (in the settings dialog), and wait for window to reload
Navigate to the Debugger panel, and click on the file name to open the file picker
Click another file name in the dropdown to open that file
Repeat a few times (rather quickly), eventually DevTools will freeze

Note: I tried to unfreeze DevTools by force-refreshing the page, it took ~minute to reload, and Chrome DevTools console filled up with the following messages:
