TYPO3 Core

I reproduced this issue using the Log module, and deleting one error entry, but I guess it affects also other parts of the backend:

The text of the message is misaligned with the icon, see the attached screenshot

I suggest to add to the CSS something like:

.media .media-left+.media-body {
   align-self:center
}

or

.alert .media{
   align-items:center
}

Plus, the text seems a bit too small (10.8px) but this could be just my opinion, this is why I would recommend to remove or override

.alert-body, .alert-message{
 font-size: .9em
}
