The question is, if the entity_id is really needed to be shown in a Lovelace UI history-graph-card (if you want to see it, you can look it up in the edit mode). Especially with this line break, it looks really ugly ...

[spacegaier]

Per the original implementation PR #7310 it is only shown for users in advanced mode which might be interested in it. But either way, this PR is just attempting to fix the overflow issue and not change the overall functionality.

You're right - wrong place to discuss that. Sorry!
