Iframe url exceeds max parameter size

Description:

When HostPageLocalStorage is true jitsi settings are stored locally in jitsiLocalStorage. The jitsiLocalStorage is passed to the iframe URL to persist settings. The features/recent-list however continues to grow in size on each refresh etc. As jitsiLocalStorage is passed to the iframe URL, and is never reset, eventually the iframe fails to load as the max parameter size is exceeded. The only way users can fix the issue is by manually clearing the local storage.

• First request features/recent-list “conference":"https://8x8.vc/vpaas- … appData.localStorageContent=null","date":1638251474303,"duration":0}”

• Second request features/recent-list “conference":"https://8x8.vc/vpaas- … appData.localStorageContent=%22%7B%5C%22features%2Fvideo-quality-persistent-storage% …”

appData.localStorageContent continues to grow with each refresh.

Steps to reproduce:

1. Open browser in incognito mode (I used Chrome)
2. Start a Jitsi iframe using “new JitsiMeetExternalAPI(jitsiDomain, jitsiOptions)”
3. Keep refreshing the page (a good 50ish+ times)

Expected behaviour:

Iframe always loads successfully.

Actual behaviour:

Iframe fails to load with parameters size exceeded

See features/recent-list size (continues to grow)

Good catch, thanks for the report!

I’d say we should stop storing items on the recent list when running in the iframe, since it’s not going to be visible anyway.
