BackwardKillWord bound to Escape,Backspace not working

Start by reproducing the Escape,Backspace chord and inspecting the behavior reported by Get-PSReadLineKeyHandler. Trace the key-handler and terminal input handling for Backspace, comparing it with the working Escape,Delete binding. Done means Escape,Backspace invokes BackwardKillWord and deletes the preceding word without breaking the other Escape bindings.

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

I believe this is a default KeyHandler, but ESC-Backspace is no longer working for me. The other handlers using Escape all seem to work (ESC-u and ESC-l to upper/lowercase a word, ESC-b and ESC-f to move forward/backword by word, ESC-d to forward kill a word, etc.). But ESC-Backspace just does ... nothing.

I set a new handler for 'Escape,Delete' to do a BackwardKillWord and that works, so it seems the problem is something with my Escape key.

My backspace in a normal terminal sends a Ctrl-H. It's been that way for years, but this stopped working a couple months ago.

Expected behavior

Pressing Escape,Backspace should delete the word before the current cursor location.

Actual behavior

Nothing happens.
