In Blink and Gecko, all three white-space settings produce the same result. In WebKit, the first setting (white-space: pre-wrap) produces a different layout when an inline element is added. 1779032 1 gsnedders 2021-07-23 04:38:26 -0700 This only affects legacy layout; LFC works correctly. 1779048 2 zalan 2021-07-23 06:42:10 -0700 It looks like we drop the word-break property for the rest of the content when we see an inline box (unless it is explicitly set on the content again e.g. <div style='white-space: pre-wrap'><b>asdf</b> <span style="word-break: break-all">alsdjfalk</span></div>) 1780729 3 webkit-bug-importer 2021-07-30 02:56:17 -0700 <rdar://problem/81317182> 2139303 4 fantasai.bugs 2025-08-28 03:29:05 -0700 We're now using LFC for almost all text content, so it seems this issue is fixed?
