[iOS] Scroll problems if you starts on text

[RayZik]

Trying to scroll the terminal window can still be a challenge if there’s a lot of data on the screen like when the screen fills with error messages. It seems you need to start your scroll with your finger in an area where there is no text. When the screen is full of text, that’s difficult. Here’s a short video demonstrating the issue. I turned on Assistive touch to demonstrate the problem.

You can see how if I try to start my scroll with my finger on some text, it ignores the scroll. If I start it where there is no text, scroll works fine.

This issue reproduces only on iOS. Android works fine.

I use xterm-addon-canvas as a workaround.
