Bug 1189389 disallowed cloning DOM objects in GetDataAsBase64 and we still use that for session history in https://searchfox.org/mozilla-central/rev/386c7f17b2421374930a447c9f424910551b659d/toolkit/modules/sessionstore/SessionHistory.sys.mjs#303. Thus the behavior is:

1. Open https://example.com
2. `pushState(new Blob(['foo'], undefined, '#blob');` on devtools
3. Close the tab (Ensure there's another tab so that this won't close the browser). This logs:
   >JavaScript error: resource://gre/modules/sessionstore/SessionHistory.sys.mjs, line 303: NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIStructuredCloneContainer.getDataAsBase64]
4. Restore the tab

Expected: There should be the corresponding navigation history
Actual: It's gone.

4. Restore the tab

Expected: There should be the corresponding navigation history, as on Chrome
Actual: It's gone.
