if there is a preview mode you can change css like this:
after that this bug will resolve:
Hey @cagrizorkol
this is a freature from a community made plugin if i am not wrong from the code-title plugin
It is best to report problems directly to the plugin author / in the plugin repository
cc: @elpnt Since you are the author of the plugin, this is probably of interest to you
Hi @cagrizorkol and @Lukas, I am the author of that plugin.
I need to rewrite the plugin, probably because the recent Inkdrop major update has changed the markdown parser spec.
As a temporary measure, you can paste the following CSS into the user stylesheet.
0.3rem y-padding works well for my MacOS environment.
.code-title {
padding: 0.3rem 0.8rem !important;
}
Just dropped code-title v3.0 
The title block is now full width to avoid bugs as much as possible.
Thank you for your support and thank you for updating plugin. 
I shared a new screen from Inkdrop which app has code title plugin new version. As you can see, fixed this style problem.
