--- Comment #46 from PhistucK <phistuck at chromium.org> ---
Right, so, the logging order is unstable between operating system versions/ports, or simply in general.
:(

So there are a few testing issues -
1. The order of console.log and beforeunload alert is unpredictable.
2. beforeunload alerts are also shown on the next test.
3. testRunner.dumpAsText() does not dump text of iFrames.
4. testRunner.dumpAsText() does not dump text across navigation (I am not completely sure about that one). 

The last three can be worked around (by removing listeners and by using console.log), but then the first one kicks in.
:(

It is a bit much for me to investigate, seeing as this is my first WebKit C++ patch (and my first C++ patch in general, I think, hehe) and seeing as I am more of a web developer and seeing as I do not have a local development machine (or a relatively fast remote development machine), or macOS.

I would appreciate assistance from experienced WebKit engineers.
