As we're touching the deps, we should monitor the editor performance after merging this PR.

I was remembering #56994 about combining block store subscriptions, and assumed it would be better to add it here rather than check on each block. Maybe the performance potential isn't worth it though. I do like the implementation though, as it makes the final result quite clean.

That's a good point about combining store subscriptions. Let's try it "as is" and watch the performance charts post-merge.

I did some smoke test with running performance in the inspector and entering into/out of zoom out mode and this method of using the combined subscription and not adding listeners was always faster in both total scripting and rendering, so I say we go with it as well.

Great. I say we merge it and then watch the performance dashboard in case of any changes post-merge.

Zoom out mode is fairly rare right now. Rather than adding a double click to all blocks, could we early return here if we're not in zoom out? That way, we only add these listeners when it's useful?

return useRefEffect(
( node ) => {
if ( editorMode !== 'zoom-out' ) {

Instead of having the editorMode as a dependency of the useRefEffect and regenerating a new ref / new event listener everytime this change. We could just call getEditorMode within onDoubleClick event listener (Like we do for useNavModeExit

This would also remove the need to pass the editorMode top/down through the context...

I'm seeing the opposite comment above. I think personally the performance impact of having the double click always there is less than re-rendering when the editorMode changes, it's also way simpler in terms of code. But I'm ok if you all disagree.

I had the same thought process. I believe @jeryj did some performance profiling on this so he may be able to answer more concretely.

I had done profiling on the page and not adding the event listener used a lot less resources. The metrics for typing are going up. I'm having a hard time isolating a PR that is causing it. It's odd to me that adding the mode to the block props would cause that, as the editing mode doesn't really change often and definitely isn't changed in the middle of the performance tests. I can make another branch that reworks this to this older style and we can compare.

#65326

@getdave the original way we did this also included passing clientId to the refEffect which would have made a difference in the profiling. We don't need that anymore, so hopefully the performance will be better now.

I don't see any major changes in performance with either approach.

The typing metic was probably affected by a new store subscription. See #65337.
