Why does chrome open an old cache version on a website?

Question

Google Chrome

The situation is as follows - I

made changes on the client's website and, satisfied with himself, went to eat, and he writes to me that I did nothing.
Standard situation - I told him - a good fellow, press ctrl + ef5 and everything will be ok. He did so, and was glad for the changes had been made. But - the next day I again ran into that the site was in the old version. We started to figure it out and it turned out - of all browsers, only Chrome saves the old version of the cache. but saves it in a very strange way -
If you merge the cache through WP, or press ctrl + f5, or open the console and reload the page by deleting the cache, then a new version of the page appears. But - as soon as you refresh the page with a simple f5, the site immediately starts opening the old version.
In incognito mode, by itself, a new version opens. Other browsers behave adequately - threw off the cache and the new version appeared and does not crawl away.
