Crash on Switch

[NullDev]

When the input box has an specific amount of lines a scrollbar appears.
If the user presses "switch" while the number of lines creates a Scollbar, the page freezes.
A reload of the page doesn't fix it. The Tab needs to be closed.

How to recreate:

1. Enter linebreaks into the input box until a scrollbar appears.

2. Press Switch.

I am still debugging but for now I am clueless.

Will be fixed once I re-coded the site from scratch. The last update was too long ago.
