Client: Node 18 Nightly CI Runs Failing

[holgerd77]

Currently the nightly CI tests on Node 18 are failing, see e.g. this CI run.

Concretely the following client tests are failing, all very concrete and deterministic tests where there is a clear behavior-not-working-correctly error message:

• not ok 45 gas limit should be double previous block
• not ok 46 baseFee should be initial value
• ok 47 should be strictly equal (on calcNextBaseFee())

This should be investigated and fixed.

Can we close this for now and re-address if it starts failing again? It looks like some sort of fluke and the tests are all passing the past 2 weeks.

Sure, please always do directly.
