n:href="foo => $bar" throws "Offset 0 on array does not exist"

[spaze]

I have a template (source) with

<td><small n:tag-if="$application->name === null"><a n:href="Trainings:application $application->id" n:attr="title => $application->company">{$application->name ?? smazáno}</a></small></td>

It gets compiled to

                echo '<a href="';
                /* line 33 */
                /** @var MichalSpacekCz\Admin\Presenters\TrainingsPresenter $adminTrainingsPresenter */
                $adminTrainingsPresenter->actionApplication($application->id);
                echo '"';
                $ʟ_tmp = ['title' => $application->company];
                /* line 33 */
                echo \Latte\Essential\Nodes\NAttrNode::attrs(isset($ʟ_tmp[0]) && \is_array($ʟ_tmp['0']) ? $ʟ_tmp['0'] : $ʟ_tmp, \false);  // <---- line 254
                echo '>';

Analyzing it on level 4 throws

Another case of the same thing, template with (source):

<small n:class="$storage->getSearchResult()->isSiteUrlMatch($site) ? search-result"><a href="{$site->getUrl()}" n:attr="rel => $noFollow" title="Go to site">{icon link}</a></small>

is compiled to

                     echo '><a href="';
                    /* line 56 */
                    echo \Latte\Runtime\Filters::escapeHtmlAttr(\Latte\Runtime\Filters::safeUrl($site->getUrl()));
                    echo '"';
                    $ʟ_tmp = ['rel' => $noFollow];
                    /* line 56 */
                    echo \Latte\Essential\Nodes\NAttrNode::attrs(isset($ʟ_tmp[0]) && \is_array($ʟ_tmp['0']) ? $ʟ_tmp['0'] : $ʟ_tmp, \false);  <--- line 516
