My server's render distance is set to 8.
My client's render distance is set to 32.

In 1.13.2, the client kept chunks loaded even if they were beyond the server's render distance, up until they were beyond the client's render distance.
In 1.14.0, the chunks disappear at a distance of just 8, despite the higher client setting. In singleplayer I can still view up to 32 chunks, so it's specifically multiplayer this affects.

Attached below are screenshots of:

• The 8-chunk distance I can see of my base when first logging in (which I would expect, unless you want to start caching chunks between logins).
• The 32-chunk distance I could see from my friend's base after walking there, with the roof of my house visible in the distance fog.
• The 8-chunk distance I can now see from the same vantage point. Can't even see the intermediary base anymore. The screenshot is taken from chunk 2,6,8 and the torch on the horizon is right on the edge of -6,4,10; so it's definitely 8 chunks and not some other value.

I'm hoping this isn't an intentional change, as I really enjoyed being able to see a long way, without my low-powered server having to generate a 32-chunk radius or send a 32-chunk radius to my friends over my slow home internet.
