Alexandre, please take a look.

Set release status flags based on info from the regressing bug 1754407

This is quite frequent https://treeherder.mozilla.org/jobs?repo=autoland&selectedTaskRun=JMFDEe71TFKQyIuF1-3g7A.0&group_state=expanded&resultStatus=success%2Ctestfailed%2Cbusted%2Cexception%2Crunnable&searchStr=linux%2C18.04%2Cx64%2Cwebrender%2Casan%2Copt%2Cmochitests%2Cwithout%2Cfission%2Cenabled%2Ctest-linux1804-64-asan-qr%2Fopt-mochitest-devtools-chrome-nofis-e10s%2Cdt8&revision=f222867fcc1da9c3c93d858d0de5b2da27526fca . It also fails on other dt jobs.

This test assert that the debugger doesn't get unexpected request while debugging a page.
But for that, we should open the page while the debugger is opened.
Otherwise the page resources might be GC-ed, forcing the debugger to fetch some content again.
