<textbox multiline="true" maxlength="140"/>

Reproducible: Always
OS: Linux → All
Hardware: x86_64 → All
Version: unspecified → 1.9.1 Branch
Summary: MAXLENGTH setting does not affected multiline input → xul maxlength attribute doesn't affect multiline xul textbox
Summary: xul maxlength attribute doesn't affect multiline xul textbox → maxlength attribute doesn't affect multiline xul textbox
This happens because a simple <textbox/> and <textbox multiline="true"/> use different bindings per: http://hg.mozilla.org/mozilla-central/annotate/9061f43b86bd/toolkit/content/xul.css#l668

<textbox/> uses html:input in as its implementation, which supports maxlength, so we're just delegating the attribute to the HMTL element:
http://hg.mozilla.org/mozilla-central/annotate/9061f43b86bd/toolkit/content/widgets/textbox.xml#l14

<textbox multiline="true"/> uses html:textarea, which doesn't support maxlength:
http://hg.mozilla.org/mozilla-central/annotate/9061f43b86bd/toolkit/content/widgets/textbox.xml#l502

(There's also inconsistency that the maxLength property applies to the multiline textboxes too, since the textarea binding extends the basic textbox binding.)
