Bug 194157 – Support line feed entities in attributes

• Status: RESOLVED
• Resolution: CONFIGURATION CHANGED
• Component: Forms

[Lanny Heidbreder]

OVERVIEW:

It would be useful to include line breaks in the placeholder attribute of a textarea element. Other browsers allow this by supporting the HTML entity for the Line Feed character, 
. But as of Safari Technology Preview 74, Safari doesn't render the entity.

STEPS TO REPRODUCE:

Create a textarea element with a placeholder attribute of "Line 1
Line 2"

EXPECTED RESULTS:

The textarea displays this placeholder text:

Line 1
Line 2

ACTUAL RESULTS:

The textarea displays this placeholder text:

Line 1Line 2

ADDITIONAL INFO:

Web Inspector displays the attribute with a space instead of the entity, while the rendered element in the browser has no space at all. However, selecting the textarea in the inspector and running $0.getAttribute('placeholder') in the console correctly displays the line break.

I changed it into following JSFiddle:

I am not able to reproduce "Actual Result" in above using Safari 16.1 and it shows similar to Firefox Nightly 108 and Chrome Canary 110.

Marking this as "RESOLVED CONFIGURATION CHANGED". Thanks!
