`theme-apple-basic`, `intro-image-right`: text continues under the image

[gy-mate]

Describe the bug

When using theme-apple-basic with an intro-image-right layout, and the text (https://wiki.openstreetmap.org/wiki/Hungary/Vasútvonalak) on the left side (formatted as h1, h2 or p) is longer than the space allocated to it, it doesn't break but continues under the image. Therefore its last part is invisible.

1. Clone this repo
