How to reproduce the bug

1. Start the project by running npm run dev.ssr
2. Click on the button Qwik is awesome

It must be the first load, just after having run npm run dev.ssr Be sure not to have multiple tabs open. If you reload the client (Cmd+R), the bug will disappear.

Console output on the client

When clicking on the button, the app crashes with the error Expected 'false' to be 'true' In store.ts, the reviveValues function has const el = getObject(entry[0]), since entry[0] is the string "null", the app crashes:

• strToInt("null") corresponds to parseInt("null", 36) and gives 1112745
• getObjectImpl will assert that objs.length is larger than the index we want to acces, which is 1112745
• assertEqual(objs.length > index, true); // assertEqual(obj.length > 1112745, true)

Questions

• How are the keys of the subscriptions computed?
