LiveChat Trigger blocks website input, so you can't click anywhere until you close the LiveChat pop up

Description:

When ussing LiveChat Trigger (the, "Hello! How can we help you?"), blocks website completely on mobile devices and partially con desktop devices. An example on rocket.chat website. Try it on a mobile device, and when the trigger pop up appears, you can't click anywhere else. You can only scroll.

Steps to reproduce:

1. Go to 'https://rocket.chat/' with an smartphone
2. Click on 'anywhere'

Expected behavior:

Visible buttons working.

Actual behavior:

You can only scroll, if you click a button that it's visible, it won't work.

In rocket.chat, using a mobile device, menu icon and 'schedule demo' and 'try now' won't work until you close the LiveChat pop up.

On PC, same thing. Anything that is on the blue box, will be blocked.

Server Setup Information:

• Version of Rocket.Chat Server: 3.16.0

The problem is between this lines (I guess). (This is with trigger activated)

If you close the pop up, it works well. (This is with trigger exitted)

Reproduce the LiveChat Trigger on https://rocket.chat/ using a mobile device and desktop browser, with the popup open. Trace the popup's interaction behavior and verify that visible page buttons, including the menu, schedule demo, and try now controls, remain clickable without closing it.
