Integration Test App X64WebDebug and Integration Test App X86WebDebug failing in CI

[TatianaKapos]

Problem Description

While cutting the 0.76 branch, I noticed that Integration Test App X64WebDebug and Integration Test App X86WebDebug have been failing in CI since Aug. 29th. The last time they passed were July 22nd meaning they broke in somehow in these series of commits: https://github.com/microsoft/react-native-windows/commits/main/?since=2024-07-22&until=2024-08-29&before=a29e4889ebab2a0a1eeb99ce66168b10e7933264+35

Edit: Narrowed it down to breaking in this commit: #13555. But doesn't seem relevant to these tests?

Currently blocking cutting the 0.76 branch. I can turn them off but unsure if these are needed to be solved before cutting a stable branch.

Example of failing build: https://dev.azure.com/ms/react-native-windows/_build/results?buildId=616086&view=logs&j=2b4cdceb-748a-5be1-3adb-8177dea64fd4&t=9627e291-1a06-5d59-b0e1-cdc421fff844

Steps To Reproduce

1. Run these tests on main
2. They will fail

Expected Results

They should pass
