// Try to disable BFCache by acquiring and never releasing a Web Lock.
// This requires HTTPS.
// Note: This is a workaround depending on non-specified WebLock+BFCache
// behavior, and doesn't work on Safari. We might want to introduce a
// test-only BFCache-disabling API instead in the future.

return new Promise(resolve => {
