Live Preview sometimes displays callout blockquote markers inconsistently

Description

In Live Preview, callout blockquote markers sometimes render inconsistently even when the Markdown content and the apparent cursor/selection position are the same.

The issue is visible with default callout syntax such as:

> [!bug]
> Bug report

> [!example]
> Example

Expected result

The Live Preview editor should consistently show or hide the leading > blockquote markers according to the same cursor/selection state.

Actual result

Sometimes the leading > marker on the callout title line is hidden while the body line marker is visible; at other times both markers are visible. The screenshots below show two examples of the inconsistent rendering state.

Screenshots

Environment

  • Theme: Default theme
  • Editing view: Source mode / Live Preview editor behavior
  • Plugins/CSS snippets: not involved in the screenshots

Notes

Reading view renders the callout normally; this seems to be a Live Preview/editor decoration refresh issue rather than a Markdown parsing problem.

I don’t see any issues on my end using the code block example above.

Maybe a screen recording of the behavior could help as well. You can paste the link as inline code or in a code block.
