screenshot 1 kmail message list doesn't display mid-eastern characters
correctly

Summary: Mid-eastern characters – such as Arabic, Persian, Urdu, Pashto,
Kurdish, etc. – do not fit in the vertical space for the characters in the
message list, resulting in broken viewing and unreadable text
Extra info: Seems like the Mid-eastern characters have been given some extra
vertical space recently – see second screenshot – across many apps in KDE
Plasma. However, this seems to have resulted in text in these characters to be
incorrectly displayed in KMail's message list, with text barely visible – see
the first screenshot (the title of the email is "اللغه العربيه" if it matters)

Steps to reproduce:
1- copy or type in the message title in Middle-eastern characters such as
Arabic and send it to your inbox,
2- see the message title in the message list, after it arrives to your inbox in
KMail 
3- the title will be barely visible, as in screenshot 1

Observed result: Mid-eastern characters are not correctly displayed in the
message list in KMail, with text in those languages almost unreadable

Expected result: Mid-eastern characters should be displayed in a manner that's
easily readable, perhaps by extending the vertical space allocated to the
message with those characters in its title, in the message list, or some other
solution

System info:
OS: Linux, KDE Neon User 5.26 (Jammy Jellyfish as base)
KDE Plasma: 5.26.2
KDE Frameworks: 5.99
Qt version: 5.15.6
Kernel: 5.15.0-52 generic 64bit
Graphic platform: Wayland, haven't tried X11 yet

Additional information:
I'm not at all sure what component is responsible for this issue, so I reported
to the closest component I could think of. Please assign to any other component
which you know is at fault.
