This library has been completely removed in NB v4, so this would no longer apply.

@MaxBear Also, FYI - While we greatly appreciate the work here, please open the issue before submitting a PR, there may be discussion needed around any proposed solution or it may be superseded by other work.

@arthanson The issue and the fix still apply for users not upgraded to beta v4 release. I have already opened the issue , otherwise, i won't have the fix id . By this

here may be discussion needed around any proposed solution or it may be superseded by other work.

do you mean one should only submit a pr after you have decided to submit a pr for this fix or not ?

@MaxBear Sorry, you submitted the issue at just the wrong time (no fault of yours) we just did the last release of 3.x before the 4.x release so there wasn't a release to get this in. That said, we are currently evaluating whether we might cut one more 3.x release and if we do we will re-evaluate potentially including your PR assuming there are not any changes needed.
