Error messages lead to stuck/unchanging pop-up in Inspect view

I just upgraded to the latest Maputnik (from 1.4, I think). Since the upgrade, I get a stream of errors in my browser console after enabling Inspect view and mousing over the map. Here’s an example:

react-dom.development.js:558 Warning: Encountered two children with the same key, `transportation_name-undefined`. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.
    in div (created by FeaturePropertyPopup)
    in FeaturePropertyPopup
warningWithoutStack	@	react-dom.development.js:558

I get a lot of these errors mentioning several of my map data layers. After mousing around briefly, the same handful of features is displayed in the Inspect pop-up no matter where I go on the map.

Anyone know how to fix this?

In case it’s relevant, I also get this error once:

Warning: Failed prop type: Invalid prop `value` of type `boolean` supplied to `StringInput`, expected `string`.
    in StringInput (created by FeaturePropertyPopup)
    in FeaturePropertyPopup
printWarning | @ | checkPropTypes.js:20

@kateler hopefully the fix in #610 solves your issue (please test and let us know), you also might want to add IDs to the vector tile features (if they are yours) as it seems to be the norm and might causes issues in other tools to plan to use. There hopefully shouldn’t be an issue using Maputnik from now on though 🤞

@kateler thanks for the test case, I can reproduce this issue with the version at https://maputnik.github.io/editor/#9.85/51.4922/719.8773, however the link @pathmapper provided https://2155-67726921-gh.circle-artifacts.com/0/artifacts/build/index.html#9.85/51.4922/719.8773 seems to function correctly, can you please confirm?
