 I don't know if Twenty Sixteen theme is still supported by WP 5.3 or if
 the theme problem should be reported here, but..

 As of WP 5.3, the Gutenberg table block is inserted within a figure tag

 {{{
 <figure class="wp-block-table is-style-regular">
 <table class=...
 ...
 </figure>
 }}}

 but only bare table is inserted in WP prior 5.3. So the CSS for displaying
 a figure tag will add extra borders in top & left in WP 5.3 with the
 Twenty Sixteen theme.

 See this link for example: [https://noyle.home.blog/2019/11/19/19/].

 There could be other blocks start getting a figure tag wrapper around
 themselves which will show a top and a left border for them. And the
 affected themes should not be limited to Twenty Sixteen.
