Created attachment 468729 [details] Test HTML page showing bug and other permutation which do not exhibit bug This is a very peculiar bug that only seems to be happening in Safari. It was discovered when trying to render Cambodian text in a flex child, though the bug exists even when displaying Roman scripts. In a Flexbox child, with a text string containing no (U+0020) spaces, IF the text: - contains an inline-block element - has zero-width space (U+200B) characters between each word - all elements are wrapped in span elements A screenshot and example HTML document for testing is being attached.
