## Description of the bug
I open the window for my notebook,
then I swap to the 2nd page of the notebook
Then I attempt to use a pen on the notebook (to write on the empty 2nd page)
but it brings up the first page of the notebook

## What's the difference with what should have happened?
swapping the page of a notebook and then using a pen should let me write in the 2nd page

## How do we reproduce this bug?
Get notebook
write on the first page
attempt to swap pages and then write in the 2nd page

## Attached logs
```
N/A
```

Start by reproducing the notebook interaction described: write on page 1, switch to page 2, and use a pen. Trace the notebook's page-swapping and pen-use behavior, then confirm that writing after switching pages changes page 2 rather than reopening page 1.
