There is an
__unstableMarkListeningStoresAPI in a data registry that allow "marking" every store that was accessed in aselectcallback:We can use the stores array to, e.g., choose which stores we need to subscribe to to get updates.
This PR changes the implementation so that:
Set()for each__unstableMarkListeningStorescall, instead of reusing one global one, and merely.clear()-ing it on every call__unstableMarkListeningStores. In that case the.add()operations are redundant.This is a spinoff from #46538, where there will be optimization opportunities: we will be able to call
__unstableMarkListeningStoresonly in very specific cases, where the set of selected stores can actually change, instead calling it for every select.
