Fix zoom overflow

[GildasMorel]

• Checkout the develop branch
• Run npm i and npm start
• Open Presenter view
• Enable touch pointer plugin by using the "plugins" menu at top right of the screen
• Click on the slide view to zoom

After zooming, the frame of the slide view goes beyond borders.
It needs to be fixed

I have already forked the project i think change the css of #current is enough, its ok if i submit the PR later so is valid for hacktoberfest?
