There was a problem hiding this comment.
@talldan this helps quite a bit! 🤔 The previous selector behavior is curious, since I didn't spot any common mistakes with redux data triggering too many updates.
I also did a quick profile while dragging on this branch. It looks like ToolbarItems render while dragging, so that might be a good spot to do a similar optimization on the navigation-link RichText in edit.js

This is beyond my skill to code review or debug, but I wanted to note that I'm seeing a navigation block error, both in trunk but also in this branch: #30177 (comment)

Nice steps @jasmussen 💖 that's a lot easier to profile consistently. |

Description
This takes us a step closer to fixing the root cause of #30177
The underlying cause is that
useNestedSettingsUpdateperforms a shallow equality check before updating a block list's settings.This combined with the way navigation link was passing through a new array for
allowedBlockson every render, causing the settings to update, resulted in a cascading render.This was compounded for some reason when using the
isDraggingBlocksselector. Still not entirely sure why that would be, but I'll continue looking into that. It might be that updating the block list settings is causing the inner blocks to re-render, which is also causing the action that updates the dragged blocks to trigger 🤷♂️ .This first step tidies up the nav link block. It might also be worth changing the way
useNestedSettingsUpdatechecks for equality. Some of the props may need more than just shallow equality.How has this been tested?
