This fixes an issue where copying text would break until changing
workspaces and consequently windows.
This *was* fixed in 0.32.0 as a result of [1], however kitty 0.33.1 with
the recent fontconfig workaround patch[2] ends up showing CJK characters
with a very thin weight, causing them to be inconsistent relative to the
surrounding text and more difficult to read.

[2]: d2c21ee297
The new version causes icons and some CJK characters to show up as
rectangle boxes. kitty prints "Too many fallback fonts" as output, and
the issue continues to occur in 0.32.1.
Probably caused by https://github.com/kovidgoyal/kitty/issues/6865 and
should be possible to fix with symbol_map in the future.
