Cannot scroll while selecting text

Describe the bug
When BTT is on, I can't scroll while selecting text. The steps to reproduce this behavior:

  1. Use one finger to hold down a click to begin selecting text.
  2. Use another finger to move the cursor to select text.
  3. Release the finger from 2., and use two fingers to scroll (the click hold by 1. still apply).

This happens only when BTT is on. I use this functionality very often because it allows me to select text outside of the screen, and adjust the selected area.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
MacBook Trackpad

Device information:

  • Type of Mac: MacBook Pro 2018 with trackpad
  • macOS version: 10.14.5
  • BetterTouchTool version: 3.04 (1163)
