Selection highlight remains on first wrapped line when dragging back to second line start with lineWrapping enabled

[lishuangfeng]

Describe the issue

When lineWrapping is enabled in CodeMirror, a visual selection rendering issue occurs specifically on Huawei tablet devices. After performing a cross-line selection (selecting across multiple wrapped lines) and then dragging the mouse/touch back to the start of the second wrapped line, the highlight on the first wrapped line fails to clear visually. Notably, the underlying selection range data is correct — the issue is purely a rendering/layout artifact. This does not occur on all devices .

I am using codemirror/view version 6.0.0

Do you know whether the browser used on that device is Webkit-based? This sounds a lot like a Safari issue (#1600, #1627), the workaround for which we're currently only enabling on Safari (version 26 and up).

Thanks for the info! Just wondering — will this workaround also be extended to other WebKit-based browsers down the line?

To determine that, it would be helpful if you could tell me a bit more about the browser used by this tablet. Can you confirm that it is Webkit-based? What user-agent string does it use?
