Rollover effect with 0.45

[phiphou]

I re-open #6278 because I don't understand the answer.

I want to be able to have multiple markers, not overlapping, and a rollover effect on either the markers or the text of the markers when displayed

Here is a sample : https://jsfiddle.net/d8qs32pw/15/ (zoom on the marker to see the second one)

It worked fine with v0.41 and older versions.

I know there is a bug with text-offset in #6146

@jfirebaugh told me to set icon-ignore-placement and text-ignore-placement on the markers layer to true but I don't want them to be overlapped.

Setting text/icon-allow-overlap to true on the hover layer as @ChrisLoer told me does not solved the problem of the weird hovering behavior.

So, I cannot use #6163 (comment)

If possible, can you update my example or tell me if v0.45 will let me have the same behavior of v0.41

It's important for me and my clients to know witch version we can use to have this needed multiple markers (not overlapping) rollover effect.

Sorry for the flood, I know you're not stackoverflow, but I think it's currently a bug.

Please don't close this before I can check the answer correctly fits my needs (and sorry for the bad english, I'm french)

Hi @phiphou, oops we've got different time-zones making it harder to talk too!

Yes, we agree it's a regression from v.41, it was introduced by the architectural changes to support "cross-source collision detection" in PR #5150. We are tracking the issue as #5836. I don't know if it will make it into the v.45 release, but I'm working on it -- and we'll keep everyone updated on that ticket. I used your fiddle to test that my proposed fix for #5836 would address your use case. I don't think you should try to use my fix yet, because it's not released yet and there's a good chance the implementation will change before release.

Thanks for your answer, I now understand better the problem, and will follow #5836.

For now I will stay with v0.41and wait for future releases to see when I can switch to an higher version.

@phiphou We closed issue #5836 as a duplicate, but the underlying issue is still something we are working on. Although the change to Mapbox GL JS is relatively simple, the change affects many other components that rely on GL JS so there has been a lot of back-and-forth discussion. The current proposed fix is at PR #6566.
