Browser monitors: window.dispatchEvent and window.addEventListener functions in application code

[nandini_balakri]

One of the consequences of MV3 (the latest iteration of the Chrome extension platform) is that if your application code overrides the window.dispatchEvent or window.addEventListener functions, you might observe missing resources or actions in waterfall data, missing results for JavaScript events, or monitor failure.

If you observe issues with browser monitor results that might be attributable to overriding window.dispatchEvent or window.addEventListener functions:

1. Confirm you using ActiveGate 1.267+, and if not, update and retest.
2. Contact Dynatrace Support to investigate further.
