Describe the bug
Link Popover position is incorrect after window resized

To Reproduce
Steps to reproduce the behavior:

1. Open https://mdxeditor.dev/editor/demo
2. Click on the link [— Daring Fireball](https://daringfireball.net/projects/markdown/), the link popover is displayed right near the link as expected
3. Click anywhere on the webpage to let editor lose focus. Make sure the editor loses focus, otherwise the bug can not be reproduced.
4. Resize the window.
5. See error: the link popover is on the top-left corner. It's expected to stay close to the link.

Expected behavior
At the last step, the link popover is expected to stay close to the link.

Mobile:

Additional context
LinkDialog.tsx fires publishWindowChange(true) when resizing happens, but link anchor is set to left:0; top:0 when editor loses focus.

To mitigate this issue, my solution is to use readOnly flag when necessary because here it uses readOnly to decide if a preview payload should be sent.

This issue is not ignorable as on Mobile and Tablet device the keyboard view will push up the viewport frequently.
