Cobertura reporter makes non valid method when using v8 coverage

[jehy]

If you use Node 12 or 13 and v8 coverage provider, istanbul generates wrong method names, including non valid < and > characters, like this:

<method name="map.<computed>.f" hits="1" signature="()V">

Bug can be reproduced with jest and with c8:
jestjs/jest#9561
bcoe/c8#149

I can try to provide a minimal example, but it seems like a simple fix would be to replace <> with < and >.

Sorry, wrong repo, actual issue here: istanbuljs/istanbuljs#527
Why is issues section open on a deprecated repo? oO
