fix: request timer reset while switching tabs

[pooja-bruno]

Description

This PR fixes an issue where the request execution timer would reset when switching between tabs. Previously, when a user initiated a request with a pre-script delay (e.g., await (new Promise(r => setTimeout(r, 10000)));), and then navigated to another tab before returning, the timer would restart from zero instead of showing the actual time.
