After blockquote, default text styles are lost

[nico3333fr]

Describe the bug
Hey, I'm one of the Proton Mail devs, we are using Rooster and we spotted an issue.

To Reproduce
When composing emails, pressing Enter to exit a quoted section can unexpectedly change the font size (e.g. from 14px to 12px) and sometimes the font itself, while the formatting toolbar does not reflect the change. The user provided reproduction steps and observed that closing a quote creates an unstyled div, suggesting inconsistent formatting inheritance and a possible UI state synchronization issue.

Steps to reproduce:

• Pressed the "Quote" button
• Typed in some text
• Key: Enter x3
• Key: Backspace x1

As you can see on snapshots after, the styling gets lost (instead of 14px, we get a weird 11.25pt value (?)). It seems the inline styles are removed.

Expected behavior
We don't loose styles in this case.

Screenshots

Thanks for any help you could provide for it. :)
Cheers,

Nicolas
