OSC 10 / OSC 11 queries report incorrect colors

[bash]

Issue description

When querying for the foreground or background color using the corresponding OSC sequences, zellij always answers with black.

For instance, when I send OSC 11 ; ? ST (query background) I receive back OSC 11 ; rgb:0000/0000/0000 ST even though I'm in a light terminal. Similarly in a dark terminal OSC 10 ; ? ST (query foreground) is responded to with OSC 10 ; rgb:0000/0000/0000 ST.

Example:

$ printf '\e]11;?\e\\' && cat -v
^[]11;rgb:0000/0000/0000^[\

Further information

I noticed that when I clean the cache directory (~/.cache/zellij) I get correct results for the first run of zellij.

Originally this issue was reported in delta (dandavison/delta#1663). Reporting this here totally fell off my radar (sorry).

Similar behaviour here. I'm using Omakub and when I've been switching themes, the NeoVim has had background=light set for some dark themes. I've checked the OSC11 response and it seems that it was wrong. After clearing the cache, all started working properly :)
