Thx for reporting.

found out that if you directly copy/paste the title without creating the textbox before, the bug does not happen.

The issue seems to happen when the clipboard contains an <h1> tag. I was able to reproduce the issue on Arch Linux with Qt 6.11.1 with the following clipboard:

[~]$ xclip -o -selection clipboard -t text/html
<meta http-equiv="content-type" content="text/html; charset=utf-8"><h1>Lagrange Polynomial Interpolation (Step-by-Step Example</h1>[~]$ xclip -o -selection -clipboard
Lagrange Polynomial Interpolation (Step-by-Step Example[~]$

Note the missing newlines.
