Chrome build visual check
This page makes the English hyphenation dictionary visible. A Chrome build with the dictionary can break the word inside a narrow measure; a build without it leaves the word intact and overflowing.
With English patterns available, the browser has legal break points and inserts line-end hyphens when the measure is tight.
Without the dictionary, hyphens: auto has no language data to consult.
The word stays unbroken and spills past the same boundary.
This specimen is rendered by the browser you are using now. Open this same file in two Chrome builds to compare their dictionary packaging.
In a dictionary-enabled Chrome build, the live specimen should wrap `hyphenation` into multiple lines with a hyphen at the line break. In a build missing the dictionary, the live specimen remains one long word and protrudes outside the bracket.
The demo keeps normal emergency wrapping disabled, so the only clean way for the word to fit is through dictionary-backed automatic hyphenation.
