                                    },
                                },

I think it is related to this update: https://github.com/vuejs/core/pull/8781

I think it is related to this update: #8781

This update only has an impact on emmed tag such as <img />、<video />、<canvas />，it won't affect custom element. For a custom element, browser doesn't support set width and height by <ext-dialog width="100" height="100" >, instead, you should set width and height by <ext-dialog style="width: 100px; height: 100px;" >

I find the problem, it caused by this commit: https://github.com/vuejs/core/commit/9845f1d2a1ea8df7ae6db7ac3e012d1989fb448b.
