[Inspector 2.0] Stack overflow error when building the new widget tree with implementation widgets #8553

A Flutter web customer with a large widget tree reported that the new inspector is crashing for them when "show implementation widgets" is toggled on.
When it crashes, they see a "stack overflow" error in the Chrome DevTools console. I've confirmed that this is due to us building the widget tree's JSON object recursively, and it seems like we are hitting Chrome's stack limit.
They've confirmed that they don't see the stack overflow error when the widget tree JSON is built iteratively instead.
