<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Comments: Fix placement of the wp_update_comment_data filter to safeguard filtered data from triggering a database error.
Introduced in <a href="https://core.trac.wordpress.org/changeset/38674">[38674]</a>, the wp_update_comment_data filter took place after the $data was sliced and prepared for the database update statement. The location of the filter assumed the result of anyone applying it would not change the data type or make structural modifications or additions to the $data array. ?\240?\159?\152?\133
This moves the wp_update_comment_data filter to take place before the $data is sliced and prepared for the database update statement.
Merges <a href="https://core.trac.wordpress.org/changeset/39640">[39640]</a> to the 4.7 branch.
Props dshanske for initial patch.
Fixes <a href="https://core.trac.wordpress.org/ticket/39380">#39380</a>.</pre>
