Hey, could you give some guidance on what needs to be done to unflag --experimental-webstorage? I tried setting this option as the default in node_options.cc and node_options.h as shown in the diff:

diff --git a/src/node_options.cc b/src/node_options.cc

This change works when running node directly:

But the tests in test/parallel/test-webstorage.js are failing and I'm not sure why. I'd appreciate it if you could give me a hint on what I'm missing, thanks!

EDIT:

The tests fail with the following error:

node:internal/webstorage:30
          throw new ERR_INVALID_ARG_VALUE('--localstorage-file',
          ^

Uh oh!
