ScopedHistory block does not work for back button

[flash1293]

Trying to block a navigation via calling scopedHistory.block does not work for back button navigation in the browser (the callback is called, but the navigation happens anyway and the URL changes).

To reproduce:

• Add

        window.daHistory = params.history;

here:

kibana/x-pack/plugins/lens/public/plugin.ts

Line 321 in 395a98b

• Go to Lens app (Visualize Library > New visualization > Lens)

• In browser console, execute

  daHistory.block('dont leave')

• Click back button

• Confirm modal is shown, but the URL changes back to /app/visualize

This is blocking the VisEditors team in moving away from the deprecated onAppLeave, which is targeted for removal by 8.8.

Discussed and decided it doesn't make sense to move forward with this issue unless we decide to set aside time for #132600.

Closing this issue for now. #132600 will remain to track the version upgrade of history
