Steps to reproduce the problem:
1. Attempt to clear the V8 cache for a page by either doing Ctrl-Shift-R, or by going to chrome://settings/clearBrowserData and selecting "cached images and filed".

What is the expected behavior?
V8 cache is cleared.

What went wrong?
V8 cache isn't cleared.

Does it occur on multiple sites: N/A

Is it a problem with a plugin? No 

Did this work before? N/A 

Does this work in other browsers? Yes

Chrome version: 55.0.2883.87  Channel: stable
OS Version: Fedora 25
Flash Version: Shockwave Flash 24.0 r0

I have been unable to reproduce the problem, and this is only a guess, but I'm pretty sure I'm on the right track.  What lead me to my conclusion:

1) There was a JavaScript problem at a certain website.  Ctrl-Shift-R, nor did clearing all cached images and files, nor did restarting the browser.

2) Restarting the browser with experiments disabled made the problem go away.

3) Restarting the browser again with experiments re-enabled brought the problem back.

4) Restarting the browser with chrome://flags/#v8-cache-strategies-for-cache-storage changed from "Normal" to "Disabled" made the problem go away again.

5) Restarting the browser yet again with V8 caching set to "Normal" did *NOT* bring the problem back.

Thus I conclude that starting the browser with V8 caching explicitly disabled (as opposed to disabling all extensions from the command line) cleared/emptied the V8 cache, when nothing else I tried to that point had.
