Blockquote formatting continues to text below horizontal line

Steps to reproduce

In the example markdown below, the highlight of blockquote continues to the text below the horizontal line. I tried several online markdown editors, and they don’t render the blockquote below the horizontal line.

> hello
___
world

hello


world

2026-04-14 19_36_46-2026-04-13 - data - Obsidian 1.12.7

Expected result

The highlight does not continue below the horizontal line.

Actual result

The highlight continues after the horizotal line.

It seems a Live preview issue; Reading view looks as expected.

If you add a new line below “hello” or above “world”, it’s fine.

> hello

world

or

> hello
