[Bug] Touch-related bug interrupts drawing

[piperone]

Hi. I've been using this library for the last few years on my PWA used primarily on iPads here. There is a bug that makes writing with a pen (like the Apple Pencil) on touch-devices using Perfect freehand a poor user experience.

To reproduce, do the following:

1. Go to your example at https://biwyi.csb.app/
2. With a stylus-device, tap once then quickly draw a line. The inputs should be [touchStart-touchStop] [touchStart-touchMove].
3. If done correctly, the second touch-action is ignored and the browser tries to focus on the closes element (not sure about the logic here). In the case of the example above, a "Share"-tooltip is displayed when using Safari, interrupting the drawing.

If you don't have a stylus, you can get similar results by tapping with your finger and holding. Keeping your finger still, the browser shows the text-magnifier, thinking you're trying to highlight text. We have touch-action: none on the SVG, so we know that ain't it.

Now, I realize that this a renderer-issue, but your example app here does not suffer from this bug and it uses the renderer from tldraw.com. I would like to see an example renderer implementation that doesn't have this issue but without being dependent on tldraw.com. Any chance of that?

Thanks for your hard work!
