Setting catppuccin_status_background to "none" show 'ugly' rounded separators around Status Session

[codeRSH]

I am not requesting help with my configuration and believe something is genuinely broken.

• Something is really actually broken.

Is there an existing issue outlining your problem?

• I have searched the existing issues and they do not solve my problem.

Describe your problem.

I did search for a similar issue, but couldn't find anything matching exactly with my issue.

## Issue 1
When doing :
set -g @catppuccin_status_background "default"

This looks fine, but the background color didn't exactly match the terminal colors, so I tried to make the tmux status background color 'transparent'

But, when doing:
set -g @catppuccin_status_background "none"

Now, the status background color exactly matches the terminal color. As you can see when setting the status background color to 'none' i.e. transparent the separators around Status session modules are showing weird black/white colors. There is no such issue around Modules on the right hand side.

## Issue 2
While changing the background color and doing refresh of the tmux config works fine within the current session, but changing the Catppuccin flavor doesn't work either after tmux config refresh or even after detaching and reattaching to the tmux session, or even creating a new one. Only way I can make the 'flavor change' work is by doing a tmux kill-server.

I am currently using iterm on MacOS, but both issue prersists across other terminals like Wezterm and Alacritty.

Paste your configuration.
