Views Link formatter mismatch between UI and validation requirements

Problem/Motivation

When configuring the Views Link field formatter, the "Trim link text length" UI prompts you to "Leave blank to allow unlimited link text lengths." However, the field validation will not allow blank values.

Proposed resolution

looking at core/modules/link/src/Plugin/Field/FieldFormatter/LinkFormatter.php

    $elements['trim_length'] = array(
      '#type' => 'number',
      '#title' => t('Trim link text length'),
      '#field_suffix' => t('characters'),
      '#default_value' => $this->getSetting('trim_length'),
      '#min' => 1,
      '#description' => t('Leave blank to allow unlimited link text lengths.'),
    );
 

Suggestions that the 'min' value is at odds with the blank requirement?

Remaining tasks

Update the code so that a blank value doesn't trigger the validation routine.

User interface changes
