I have implemented a custom math node in my ProseMirror project (using katex). Up until this point, whenever such a node was selected, the content within the node was not highlighted in blue (as usual text selections are). But since I've upgraded from 0.18 to 0.21 this started happening.
Any idea how I can I avoid the blue highlighting? I.e. how can I get what's on the left instead of what's on the right, when I select a node?
