Bug: wrongly switch to another site note

[ReporterX]

• Browser version: 66.03
• Extension version: 1.2.7
• Operating system: Windows 7

Steps to reproduce:
Setting: Number of tabs = 5
Open sidebar / toolbar popup.
Open site A on the first tab.
Create a note in Tab 1 (URL/domain note)

Then open site B on the second tab.
Select to view site A note (URL/domain note).
Click on "Tab 2" in sidebar note.

Expected: Stay on the same note (i.e. site A note - Tab 2)
Actual: It switches to the current site domain note (i.e. site B domain note).

Example

Open a new tab. Visit Google and create a note.

Open another new tab. Visit Yahoo. Select www.google.com note.

Click "Tab 2". It should still stay at www.google.com note.
But it switches to us.yahoo.com note unexpectedly.

I could've sworn that was an issue in a previous version that I fixed. Thanks for pointing this out, I'll look into it.
