Bug fix -
* Issue where comments were truncated in the sidebar mode with no option to expand them

This change enables the scrollbar in the Sidesy popout. I had a few users reach out with this suggestion, so testing it out :)

v1.3.3
- Sidesy now remembers where you last placed the comments and loads them there for new tabs/windows
- Added theatre-mode handling. Comments go to their default place when theatre-mode is on.
- Toggling comments to the sidebar while in theatre mode switches viewing to default mode.

Bug fixes -
1. Horizontal scrollbar appearing on smaller screens
2. Comments being truncated when switched to sidebar view
