• Status: RESOLVED

• Component: HTML Editing

Test case

See attached test case (also available at http://persistent.info/webkit/test-cases/content-editable-wrap-trailing-space.html)

The space disappears when the current line is as wide as the editable area, and the space causes it to start wrapping. The "word-wrap: break-word;" property for all contentEditable elements appears to be implicated, overriding it to "word-wrap: normal" causes the bug to go away.

Reproduced in Safari 11.0.2 on High Sierra and an archive build at r227011 (the oldest builds I could find also had the bug, so this is not a recent regression).

I am able to reproduce this bug in Safari 15.6 on macOS 12.5 using attached test case and it shows following:

beforeinput content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax'
      input content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax<nbsp>'
beforeinput content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax<nbsp>'
      input content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaaxa' <<<<< (NOT SPACE)

*** Firefox Nightly 104 ****

beforeinput content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax'
      input content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax '
beforeinput content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax '
      input content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax a' <<< SPACE before 'a'

*** Chrome Canary 106 ***

beforeinput content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax'
      input content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax<nbsp>'
beforeinput content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax<nbsp>'
      input content: 'aaaaiiiiaaaaaaaaaaaaaaaaaaaaaaaaaaax a' <<<< SPACE before 'a'

Let me know if I am testing incorrectly. Thanks!
