Fixes #9731

this PR fixes issue #9731 where data exported from the Performance screen was missing the most recent timeline events. Timeline events are only pulled from the VM every 10 seconds, so frames drawn after the last poll were exported without them. Now the latest timeline events are pulled before exporting, the same way the Network screen does with fetchFullDataBeforeExport.

Before

most recent frames (1331–1411) had no timeline events in the file.

After

all of them had timeline events, including the most recent frame
