Description

Under some circumstances, the text overflows the container.

Step-by-step reproduction instructions

By pasting a long text

• Copy this text:

Lorem ipsum is a dummy or placeholder text commonly used in graphic design, publishing, and web development. Its purpose is to permit a page layout to be designed, independently of the copy that will subsequently populate it, or to demonstrate various fonts of a typeface without meaningful text that could be distracting. Lorem ipsum is typically a corrupted version of De finibus bonorum et malorum, a 1st-century BC text by the Roman statesman and philosopher Cicero, with words altered, added, and removed to make it nonsensical and improper Latin

• Paste into a stretchy text paragraph.
• Publish the post.

Observe how the text overflows the container both in editor and front-end.

Manually entering a long text

Alternatively, you can try the same manually. Observe how the text is adjusted until it stops doing so:
