Created attachment 183709 [details]
Example of unreadable reply

KMail: 6.4.3 (25.04.3)
Environnement de développement de KDE: 6.16.0

This is also affected by the "window wrapping bug" (https://bugs.kde.org/show_bug.cgi?id=219572)

Here are some steps to reproduce the issues:

First mail, line wrap at 78 chars, big window, everything work as expected, I compose and receive exactly this:

```
Lorem ipsum dolor sit amet consectetur adipiscing elit. Quisque faucibus ex sapien vitae pellentesque sem placerat. In id cursus mi pretium tellus duis convallis. Tempus leo eu aenean sed diam urna tempor. Pulvinar vivamus fringilla lacus nec metus bibendum egestas. Iaculis massa nisl malesuada lacinia integer nunc posuere. Ut hendrerit semper vel class aptent taciti sociosqu. Ad litora torquent per conubia nostra inceptos himenaeos.
```

First reply, line wrap 78 chars, big window, again, everything work as expected, I compose and receive exactly this:

Lorem ipsum dolor sit amet consectetur adipiscing elit. Quisque faucibus ex sapien vitae pellentesque sem placerat. In id cursus mi pretium tellus duis convallis. Tempus leo eu aenean sed diam urna tempor. Pulvinar vivamus fringilla lacus nec metus bibendum egestas. Iaculis massa nisl malesuada lacinia integer nunc posuere. Ut hendrerit semper vel class aptent taciti sociosqu. Ad litora torquent per conubia nostra inceptos himenaeos.
```

Second reply, line wrap 78 chars, big window, it starts to be broken, I receive this:

Lorem ipsum dolor sit amet consectetur adipiscing elit. Quisque faucibus ex sapien vitae pellentesque sem placerat. In id cursus mi pretium tellus duis convallis. Tempus leo eu aenean sed diam urna tempor. Pulvinar vivamus fringilla lacus nec metus bibendum egestas. Iaculis massa nisl malesuada lacinia integer nunc posuere. Ut hendrerit semper vel class aptent taciti sociosqu. Ad litora torquent per conubia nostra inceptos himenaeos.
```

All subsequent reply are more and more broken, and after a few replies, here is the result:

Expected Behavior:

The original message should not be hard wrapped.

Actual Behavior:

The text is hard wrapped at 78 characters. This is problematic for two reasons:
- It completly broke the readability (no > prefix)
- Even with the prefix, after few replies you get this kind of unreadable content:
```
>>>>>> Lorem ipsum dolor sit amet consectetur adipiscing elit.
Quisque
> faucibus
>> ex
>>>>>> sapien vitae pellentesque sem placerat. In id cursus mi
pretium
> tellus
>> duis
```
