Time of current loading requests reset when switch to another request

## Expected Behavior
While loading request 1 and switch to request 2, when switch back to request 1 and keeps loading it must return the current time of loading.
## Actual Behavior
When switch back, it resets the time and start counting seconds again.

## Reproduction Steps
1. Do a http request within infinite timeout to response
2. While loading and time start to count, change to another request
3. Go back to the request of step 1

Start by reproducing the request-tab switching sequence in Insomnia with a request that has an infinite timeout, then trace where the loading duration is tracked when switching requests. The issue is done when returning to an in-progress request preserves its elapsed loading time instead of restarting the counter.
