Fixes #31089
BBCode tags are added as separate Items in the Item tree. Each item is treated independently when considering wrapping, even if there are no breakable characters (whitespace, separatable kana) between them.
This change fixes that by calculating the width of the following items up to their first breakable point and adding that to the width for the purpose of wrapping the line.
