vector tiles no longer work with latest openlayers

[karussell]

when reloading the page with e.g. &layer=Mapilion it gives:

Uncaught TypeError: this.targetContext_ is null
    resetDrawContext_ VectorLayer.js:258
    renderDeferredInternal VectorLayer.js:293
    renderDeferred Layer.js:368
    renderDeferred Layer.js:407
    declutter Composite.js:180
    declutter Composite.js:179
    renderFrame Composite.js:150
    renderFrame_ Map.js:1601
    animationDelay_ Map.js:1455

Will be likely fixed via openlayers/openlayers#16879

The upstream fix has been merged and was included in 10.6.0 release:
https://github.com/openlayers/openlayers/releases/tag/v10.6.0

And that release was made ~2 months ago,
so I believe openlayers dependency could be updated again? :)
