// Test for https://github.com/ether/etherpad-lite/issues/1763
// This test fails in Opera, IE and Safari
// Opera fails due to a weird way of handling the order of execution,
// yet actual performance seems fine
// Safari fails due the delay being too great yet the actual performance seems fine
// Firefox might panic that the script is taking too long so will fail
// IE will fail due to running out of memory as it can't fit 2M chars in memory.
// Just FYI Google Docs crashes on large docs whilst trying to Save,
// it's likely the limitations we are
// experiencing are more to do with browser limitations than improper implementation.
// A ueber fix for this would be to have a separate lower cpu priority
// thread that handles operations that aren't
// visible to the user.
// Adapted from John McLear's original test case.

// JM commented out on 8th Sep 2020 for a release, after release this needs uncommenting
// And the test needs to be fixed to work in Firefox 52 on Windows 7.
// I am not sure why it fails on this specific platform
// The errors show this.timeout... then crash the browser but
// I am sure something is actually causing the stack trace and
// I just need to narrow down what, offers to help accepted.
