let's say I have a vector layer created from 2 features.
- The vector layer has style set to green color.
- There is a select interaction with a style set to red color (in other words, I want to click on a feature and make it turn red).
- I set style of one of the features to blue color by calling feature.setStyle().
If I select the green feature, it shows up red.
If I select the blue feature, it stays blue.
Is that correct behaviour?
