Clearing cache & block sync state

[grod220]

When clearing cache, the last block synced status does not clear until a new block is synced. This can cause feelings of unresponsiveness. In case of mainnet, genesis state sync can take some time so it accentuate this feeling. Example:

compressed.mov

Likely need to explicitly reset the chrome.storage.local value for lastBlockSynced when issuing a cache clear action.

duplicate of penumbra-zone/web#1496.

previous offline discussions suggest the fix may be more involved, but I will investigate.

chrome.runtime.reload() restarts the extension by terminating and reloading the background service worker and injected content scripts. Immediately after reloading the webpage, it causes a redirect to the "Connect to Penumbra" page (see example in penumbra-zone/web#1496). As L pointed out, restarting the background worker breaks the injected content scripts, and the constrained single-threaded service worker blocks the listeners responsible for initializing the content scripts.

Wouldn't refactoring the service worker lifecycle automatically resolve this issue as a side-effect? The only additional modification would be to the promise in the message listener by updating it with:
await Promise.allSettled([localExtStorage.remove('params'), indexedDb.clear(), chrome.storage.local.remove('fullSyncHeight')]);

I think if we want to tackle this in isolation, we’d need to ensure that the wallet connection status, which is handled by a content script, persists during chrome.runtime.reload(). We can save the connection status in persistent storage, chrome.storage.local. And when the extension and content scripts are reloaded, we can restore the wallet connection status from there?

Yes, I think that allSettled() line would resolve the issue and can be done now

even with that line, it will immediately display a "data objects could not be cloned causing transactions to fail" error. Then, if you try refreshing the screen, it redirects to the "Connect to Penumbra" page – see video example in penumbra-zone/web#1496.
