ESVU Chakra installation fails in CI

[ptomato]

As if we hadn't just fixed one of the other CI jobs ... Chakra has started failing since yesterday.

I can't reproduce this failure locally, ESVU's test passes fine.

Any suggestions?

Another datapoint - test262.fyi's ChakraCore test runs have been extremely flaky since the beginning of November and stabilized at a vastly lower score a couple of days ago. The last upstream commit is from March, unfortunately I have no idea what's happening either.
