Summary:
Given that we have to retry aggressively to fetch reduciton traces the blok augmentation can take a longer time. For cases like embedded bloks this can slow down the ui debugger even if you arent debuggin bloks. To avoid this we display the frame immediatley and then asynchronously augment it.
There is a possibility that you might see bloks bound tree nodes with no name briefly since this is this the state they come from the client as.
This isnt the ideal solution as the better way would be to do the unminification first and then add the derived components (which depends on reduction trace) after. This avoid this qurik but is a much bigger refactor so will do it another time if needed
