Fixed Custom warning title > 255 characters is silently truncated

<xf:radiorow name="warning_definition_id" value="0"
    label="{{ phrase('warning_type') }}">

    <xf:foreach loop="$warnings" value="$warning">
       <xf:option value="{$warning.warning_definition_id}" class="js-FormFiller">{$warning.title}</xf:option>
    <xf:option value="0" class="js-FormFiller"
       label="{{ phrase('custom_warning:') }}">

       <xf:textbox name="custom_title" maxlength="{{ max_length($warning, 'title') }}" />

$warning is a XF:WarningDefinition, and not an XF:Warning as such max_length is returning null, and no max length is being applied. And then the XF\Entity\Warning::title property has forced set so it is silently truncating the title if it is too long.

The correct bits should be: maxlength="{{ max_length('XF:Warning', 'title') }}"
And likely remove the "forced" attribute for the column/property so a message is returned if too long data is actually sent to it

Thank you for reporting this issue, it has now been resolved. We are aiming to include any changes that have been made in a future XF release (2.2.13).

Change log:
Fix max length attribute of custom warning title input
There may be a delay before changes are rolled out to the XenForo Community.
