bug#45380: 28.0.50; Error in coloured output in Emacs 28.05(AUR package: emacs-git)

[Utkarsh Singh]

In the attached screenshot I am trying to compare eshell behaviour
for 2 colored outputs. On the left hand side 'pacman -Ss emacs' command
generates a small coloured output which works as expected but on the
right hand side 'yay -Ss emacs' generates a fairly large output in which
half of the colour in distorted. Screenshot have been obtained using
'emacs -Q' command.
