`truncateThreshold: 0` prints `process` and triggers DeprecationWarning

[jendrikw]

Using node v20.19.1,

I get a deprecation warning because chai access the property _channel from process.

(node:495) [DEP0129] DeprecationWarning: _channel is deprecated. Use ChildProcess.channel instead.

i suspect this is out of our control and happening just because we iterate over all members of an object being asserted against

if some of those are deprecated, we will trigger deprecation warnings i guess

if you could reproduce this in node, that'd be very helpful. struggling to trace it in stackblitz. a basic script that causes this in node would be helpful

I think the terminal scrollback buffer of stackblitz to too small for this. If you run npm run test:run >& test.log, you can see the deprecation warning in the log file.

i more mean its difficult to debug the problem in stackblitz and it doesn't seem to happen the same in node

so a reproduction that runs in basic node, unrelated to stackblitz, would be very helpful
