Change Details

I've been trying to automate to get the same problem as in T358380: The user is on a mobile phone, switch to desktop, click on the TOC and get high first input delays. If I connect my phone to my desktop computer and inspect using devtools, I get the high "Input delay" on my interactions. I put a trace here: https://trace.cafe/t/pE7T9jvEiH However when I try to automate the same, doing the exact same steps and clicking on the TOC, I get the interactions but not the same Input delay. Using automation that is only 6 ms and not 100+. I tried clicking on different elements to make sure I mimic it correctly but no luck. Let me add trace with some clicks. I want to be able to reproduce it so we in the future could have performance regressions tests to find regressions.
