Smartphone (Android) - Backspace not working as expected

[SciLor]

If I am using my smartphone to write into the terminal, it is working as expected except that the backspace isn't working

If I write beep and press backspace it gets beepbee, another backspace beepbeebe, then beepbeebeb. after that it is possible to remove all chars by pressing backspace often enought.

You may reproduce it with that html file.

I had the same sort of issue on Linux yesterday. While I was trying to make a patch for #50 I must have bumped something. At the time I took the screenshot it was fine, but now when I press any key (not just backspace) in multiline mode it repeats the previous line a bazillion times but still somehow maintains the correct input.

All I was trying to type was the red part -- but it kept repeating the first line every time I typed a key.

I think I may have a fix for the problem of repeating the first line:

local-echo/lib/LocalEchoController.js

Line 298 in 8d0b7f5

this.term.write("\r");

-this.term.write("\r");
+this.term.write(`\x1b[${this._termSize.cols}D`);

I forgot I had convertEol: true in the terminal options. It must have been converting the \r to a \r\n and pushing the cursor down when it shouldn't.

As to your problem @SciLor I have no idea what's going on there.
