iTerm2 highlighting pasted text

I recently switched to a new machine, and I'm noticing a behavior in iTerm2 I haven't seen before. Whenever I paste text into iTerm2, the text is highlighted:
enter image description here

Here, I pasted "err". Why is this, and what is it signifying?


Solution 1:

There is nothing to worry about. If you just click the space and then delete button. The highlight disappears as soon as you do this and whatever has been pasted will run.

Let me know if it is ok.

Thank You!
