So this should now be merged with #500?

[olegshtch]

I suppose this PR should be merged before to get clean CI.

[MasonProtter]

These changes aren't compatible with Observables v0.4, so we need to drop compatibility with it and only support v0.5. Also, Observables.listeners is used in two additional places here that need updating. I've proposed these changes as a PR to your PR branch here: olegshtch#1

[halleysfifthinc]

This is great! I think we should probably keep the various PR's separate as much as possible. Are the changes for Observable listeners necessary to get tests passing again?

I'm not very familiar with javascript, but the changes look reasonable. Changing the minimum tested Julia version to 1.6 LTS LGTM, but we should also change the julia compat entry to 1.6 as well (or drop 0.7 at the very least).

We might also want to hold off on the WebIO version bump given other current PR's that could form a more substantial minor version release.

[olegshtch]

@halleysfifthinc No, Observable listeners don't related to tests. Sounds reasonable, I've removed additional commits.

[MasonProtter]

Those commits about listeners are required to fix InteractBase.jl for me. Is the idea here to do those changes in #497? What's wrong with just doing them together?

[halleysfifthinc]

My thought was to keep PRs separate and as small as possible, which is often preferred by maintainers (but I don't know for WebIO maintainers). I'm equally invested in getting #497 merged (along with #498) to fix PlotlyJS plot updates in Jupyter.

[halleysfifthinc]

In case there was any confusion, my suggestion was to reduce the scope of this PR to solely fix the frontend tests, and remove both mine and @MasonProtter s contributions for fixing #497 from this PR. Multiple currently open PRs (#500, #497, #498) would benefit from having the master branch passing tests again.

The reduced scope could be a quicker/easier merge.

[olegshtch]

Removed all commits not related to frontend.

[fonsp]

Does someone understand the test failures? Is it related to this PR?

[olegshtch]

@fonsp Yes, this PR fixes test failure in bundling.jl

[halleysfifthinc]

The remaining test failures are unrelated to bundling and are solved by #497.

[MasonProtter]

Seems really weird to me to split up the fixes into two separate PRs, since now we have two PRs where the tests don't pass rather than one PR where all tests pass.

[MasonProtter]

Regardless, @pfitzseb, @travigd, @shashi or @timholy could someone merge this? This and #497 are ready and if taken together get all the tests passing

[MasonProtter]

Thanks @pfitzseb, would you mind triggering the JuliaRegistrator? @fonsp added me to the repo but I'm not allowed to commit or trigger the registrator.
