<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>Since commit <a href="https://git.drupalcode.org/project/html_title/commit/6c141e48dcbbcfd9b4f0cdce5b4f66138d92d1d5">6c141e48dcbbcfd9b4f0cdce5b4f66138d92d1d5</a> released in 8.x-1.2 my node titles are surrounded by lots of <code><br></code> tags (and consequently loads of unwanted whitespace), when they are being displayed in non-Full view modes (such as teaser listing Views, but I've noted this in other view modes too).</p>
<p>Specifically, this change:</p>
<pre> function html_title_node_view(array &$build, EntityInterface $node, EntityViewDisplayInterface $display, $view_mode) {<br> if (isset($build['title'][0]['#context']['value'])) {<br>- $build['title'][0]['#context']['value'] = \Drupal::service('html_title.filter')->decodeToMarkup($build['title'][0]['#context']['value']);<br>+ $build['title'][0]['#context']['value'] = \Drupal::service('html_title.filter')->decodeToMarkup($build['title']);<br> }<br> }</pre><p>Where the original code would produce:</p>
<pre>Drupal\Core\Render\Markup {#2036 ▼<br> #string: "Home"<br>}</pre><p>The new code produces:</p>
<pre>Drupal\Core\Render\Markup {#2348 ▼<br> #string: """<br> <br><br><br> <br><br><br> <br><br><br> <br><br><br> <br><br><br> <br><br><br> <span property="schema:name" data-quickedit-field-id="node/22177/title/en/full">Home</span><br><br><br> <br><br><br> <br><br><br> <br><br><br> """<br>}</pre><p>The <code>$build['title']</code> array being processed is along the lines of this:</p>
<pre>array:18 [▼<br> "#theme" => "field"<br> "#title" => "Page heading"<br> "#label_display" => "hidden"<br> "#view_mode" => "full"<br> "#language" => "en"<br> "#field_name" => "title"<br> "#field_type" => "string"<br> "#field_translatable" => true<br> "#entity_type" => "node"<br> "#bundle" => "page"<br> "#object" => Drupal\node\Entity\Node {#1169 ▶}<br> "#items" => Drupal\Core\Field\FieldItemList {#1805 ▶}<br> "#formatter" => "string"<br> "#is_multiple" => false<br> "#third_party_settings" => []<br> 0 => array:3 [▼<br> "#type" => "inline_template"<br> "#template" => "{{ value|nl2br }}"<br> "#context" => array:1 [▼<br> "value" => "Home"<br> ]<br> ]<br> "#cache" => array:3 [▶]<br> "#weight" => -5<br>]</pre><p>I note the <code>nl2br</code> twig filter which is undoubtedly responsible for producing the <code><br></code> tags, but I have no idea where the newlines are coming from in the first place, as they're not present in the value, and this isn't happening in the full view mode. The code responsible for wrapping <code><span property="schema:name" data-quickedit-field-id="node/22177/title/en/full">...</span></code> around the value doesn't seem responsible (looks like that is <code>quickedit_preprocess_field()</code>), and nor does the title template (in my case it's <code>core/modules/node/templates/field--node--title.html.twig</code>).</p>
<p>This patch seems to work around the issue for me:</p>

<p>I also note the typo in the header comment for that function. There seem to be multiple typos like this in the comments.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>Try making a View of teasers?</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>I think my suggested patch is sensible regardless, but it would also be good to know why these values are getting surrounded by newlines in the first place.</p>
