GUI is slow to respond

Something, I believe in the Tech Demo, makes the app initialize and react slowly in a browser.

• This is making GUI development much less smooth.
• I believe there's an important learning opportunity here: We should find out why this is happening so we can prevent creating more sluggish code.

How to reproduce

1. Load the app in a web browser
2. Click some button repeatedly until it reacts

Actual behavior

• Observe that it takes up to 20 seconds for it to work the first time.

Expected behavior

Button clicks result in instant reaction.
