Unnecessary HTML attributes

Hi, the simplest fix I found was simply to check the value is not empty and set the attribute to NULL if it is:

diff --git a/block_title_link.module b/block_title_link.module
index c56cfba..351ec7e 100644
--- a/block_title_link.module
+++ b/block_title_link.module
@@ -93,8 +93,8 @@ function block_title_link_preprocess_block(&$variables) {
         '#title' => $blockLabel,
         '#url' => Url::fromUri($tileLink),
         '#attributes' => [
-          'target' => $linkTarget,
-          'title' => $linkTitle,
+          'target' => $linkTarget ?: NULL,
+          'title' => $linkTitle ?: NULL,
         ],
       ];
     }

The attributes are then not rendered if the value is NULL.
