When annotating twice the same content only the first annotation is shown when clicking on the small yellow icon

Steps to reproduce:

1. Select the text you want to annotate on a page
2. Press CTRL+M and write some text
3. Click on "Add annotation"
4. Repeat steps 1-3 on the same text selected before
5. Click on the small yellow icon

Expected results: Only the newer annotation is visible when clicked on the small yellow icon.

Actual results: The first annotation is shown each time.
