Can someone help me to find the cause? There isn't any error in error console...

Thank you!

Confirmed here with PM 28.11 and Unstable-2020.07.26, default and new profiles (Win7 x86).
Clicking on the small, blue tiles on the map has no effect.

As reported, nothing in Error Console.

In Firefox 68, clicking on any tile produces an informational popup like this:

Edit:
This site uses v.2 of the polyfill.io script, which always causes problems.
However, neither blocking that script, nor adding a user agent override for polyfill.io made any difference at all (which normally, either one removes the problem), so either that's not the cause, or perhaps something has changed with how polyfill.io behaves.

For what it's worth you can force a polyfill by appending &flags=always to the CDN url. It appears that it is not properly detecting the PM UA However, the problem here goes deeper than that from what I can tell.
It doesn't work in Webkit or pre-Servo Firefox either, so I filed a bug. (The library claims to even support old IE, so here's hoping.)

Thank you. Viglino already answers to the ticket: this is a openlayers v6.4.0 "problem":

Pointer events polyfill removed

Now that all major browsers support Pointer events natively, we removed the elm-pep dependency. If you are targeting older browsers that do not support Pointer events, you now need to include a pointer events polyfill (elm-pep or pepjs) in your application.

I try with both elm-pep and pepjs and work ok with both.

Thank you

I'm not sure the degree of implementation in-tree, but we do have preliminary Pointer events functionality that works, it's just pref'd off.

Try it out: about:config ->

Code: Select all

dom.w3c_pointer_events.enabled;true

It works on the test page here.

Try it out:

Yes, works for me too on the page OP linked.

Yes, thank you. Work also for me. Good to know. But why is not enabled by default?
