CSS: weird interaction between img with max-width and other elements causes
parent element width to go berserk

<style>span::before { content: '\A'; white-space: pre-line; }</style>
<div style="width: max-content"><img>X <span>X</span></div>
The div should be one X wide. Instead it was one X plus a trailing
space wide.
When a forced line break sits in its own whitespace-only RenderText
(here, generated by ::before content: '\A'), trimmedPreferredWidths
early-returns without copying m_hasBreak into widths.hasBreak. The
caller never sees the forced break and skips the trailing-whitespace
trim added for in-text \n.
