Because libxcb-1.11 predates the fix, see comment #18

> Are there any plans to make a fix for this?

The fix is made of 2 different patches for 2 different packages.

1. XCB needs to expose the 64bit sequence number by an API addition, this is
comment #18

2. Xlib needs to make use of it, that's a separate (bigger) patch for libX11.

But for #2 to happen, it requires an official release of libxcb that includes
#1 (not 1.11) so that libX11 can depend on the appropriate XCB version that
exposes the 64bit API.
