Keyboard enter on focused cluster won't zoom into it

[cftarbay]

• I'm reporting a bug, not asking for help
• I'm sure this is a Leaflet.MarkerCluster code issue, not an issue with my own code nor with the framework I'm using (Cordova, Ionic, Angular, React…)
• I've searched through the issues to make sure it's not yet reported

---

How to reproduce

• Leaflet version I'm using: 1.4.0
• Leaflet.MarkerCluster version I'm using: 1.4.1
• Browser (with version) I'm using: Chrome 71.0.3578.80
• OS/Platform (with version) I'm using: Windows 10 1709

What behaviour I'm expecting and which behaviour I'm seeing

When I tab across and focus on clusters in a map, and then hit enter to zoom in on one as I would on a click, it does not work when using leaflet version 1.4.0 or 1.3.1. If I change my version of leaflet back to 1.0.3, it does work as expected.

Minimal example reproducing the issue

I just changed the leaflet version used in the 388 point example in this library to version 1.4.0, and this produces the bug. I put it into plnkr, and if you change the version back and forth you can see the issue.

• this example is as simple as possible
• this example does not rely on any third party code

Hm, this should be handled by leaflet for us.

Does this reproduce with standard leaflet?
If you make a marker and add a click listener, can you focus it and use enter to click it?

The answer is kind of...
It's currently only handled by L.Popup. Leaflet doesn't emit a click-Event when Enter is pressed.

I've build an example to show the current behavior:

Thanks.
This sounds like a leaflet regression/change then. Please open an issue at leaflet/leaflet and link them back here.

As a workaround you could add a keypress listener and call the zoomTo... method when an enter key is pressed.

Are there any news regarding this? Has a bug been filed against the Leaflet project?
Just did a quick test, this hasn't worked since version 1.0.3 of Leaflet.
