Is your feature request related to a problem? Please describe.
It looks like in blizzard infinite wisdom (so to speak) they have decided to extend the shader option of the chat background to the whole chat, including the sub-category of the combact log chat titles

Describe the solution you'd like
can you exclude once again the upper tab (where the names are) from the background shader so we can have a darker background for easier reading?

Additional context
As always, when blizzard create or break something it comes to the hands of smart addons developer to handle thing the right way!
