Does anyone else having a Broken Heart Symbol (
) along with the selected line?
I can’t figure out why it is appearing in the editor.
I guess, this is coming with some plugin, but I am unable to figure out which plugin is it.
Whichever line is selected, or you are editing, this symbol appears there.
Here is the screenshot:
I want to know why it is appearing. And if I’m not doing anything wrong, then it shouldn’t be displayed.
Thanks
The troubleshooting steps About the Bug reports category - #11 by system are linked in the template when you create a new topic.
I’d try those.
I thought, it is a feature either coming with some Community Plugin or part of Obsidian and it might be indicating something…
Still not sure, if it is a Bug…
So, I used tips from the link shared in @ariehen 's reply i.e. About finding Bugs, and finally found the plugin which is responsible for this Heart Break Symbol. This is Obsidian Card Note Plugin.
For this, I moved all the plugin folders from .obsidian/plugins to a separate folder and then reloaded the app. The by moving one plugin folder at a time and reloading the app, I finally found Obsidian Card Note Plugin. This plugin is using the
symbol by default. Phew… 
BTW, its quite a useful plugin, especially if you use your notes references in Canvas or ExcaliDraw …
