History Slider: Not showing (unsaved) versions

### Details:
1. Add a new note
2. Add a line of text (random)
3. Wait 3 seconds for the Save OP to take place
4. Add a new line with text
5. **Quickly** press the Versions Slider (top right corner)

As a result, the newly unsaved version (containing the text inserted in (4) will not be accessible thru the picker.

Thank you @diegoreymendez for spotting this one!!


Start by reproducing the five steps in the issue, focusing on the Versions Slider in the top-right corner immediately after adding the second line. Trace the history/version-picker entry point involved in that interaction; done means the newly unsaved version containing the added text is accessible through the picker.
