"Poster-like" section looking broken in the front-end

[juanfra]

Description

When adding the poster-like section pattern in a page, and then viewing the page in the front-end (in large viewports > 1900px width), the text is breaking in several lines and the design looks broken.

Step-by-step reproduction instructions

1. Add a page.
2. Add the "Poster-like section" pattern.
3. View the page in a viewport that's bigger than 1900px width.

Column widths changing to 80 / 20 fixes this issue, I put in a PR for this in case it's an acceptable solution from a design point of view. Visually, nothing else changes.
