@shaodahong , have you got some comment to review?

[shaodahong]

Can we judge mobile?

[PavelRazumov]

@shaodahong , what do you mean? I don't understand, in a mobile view, body is also present in the DOM

[shaodahong]

Maybe should if (isMobile && container === document.body).

[PavelRazumov]

@shaodahong , It's bug actually for safari browser, for example, on IPhone (mobile device ) and IPad (tablet device) this defect is present, and i checked work of these devices, but don't know about Mac

[shaodahong]

In my desktop browser, everything is normal, so my suggestion is to add this fix to the mobile browser.

[PavelRazumov]

[PavelRazumov]

@shaodahong , I checked on IPad with isMobile() flag and work incorrect

[PavelRazumov]

@shaodahong on Tablet devices isMobile() -> return false

[shaodahong]

I checked on IPad with isMobile() flag and work incorrect

Yep, so we need judge like this

const isIosDevice = (/iP(ad|hone|od)/.test(window.navigator.platform)

if (isIosDevice) {
//...
}

[PavelRazumov]

@shaodahong, on IPad devices now platform return MacIntel

[shaodahong]

We need support ssr, so

Suggested change

	const isIosDevice = /iP(ad|hone|od)|MacIntel/.test(window.navigator.platform);
	const isIosDevice = canUseDom() && window.navigator &&
	window.navigator.platform &&
	(/iP(ad|hone|od)/.test(window.navigator.platform) ||
	(window.navigator.platform === 'MacIntel' && window.navigator.maxTouchPoints > 1))`;
