 * Hello!
    First, thanks for this great plugin. I heavily use the summary block 
   in my site. However, there’s a small problem with the block. This block can be
   inserted into post and works well. But, the next time I reload the post to edit,
   this block always shows a notification “This block contains unexpected or invalid
   contents”. The developer console (chrome) shows an error “Block validation: Block
   validation failed for `advgb/summary`“: Expected:
 * <ul class=”wp-block-advgb-summary advgb-toc alignnone”><li class=”toc-level-1″
   style=”margin-left:20px”>[A header goes here](https://wordpress.org/support/topic/summary-block-error-when-reloading-post/?output_format=md#advgb-toc-7de9f912-c695-473a-b600-166bbc985751)
   <li class=”toc-level-1″ style=”margin-left:20px”>[A header goes here](https://wordpress.org/support/topic/summary-block-error-when-reloading-post/?output_format=md#advgb-toc-c600210d-4cf6-40c3-998b-4eaffeca6481)
 * Actual:
 * <div class=”wp-block-advgb-summary alignnone”><div class=”advgb-toc-header collapsed”
   >Nội dung</div><ul class=”advgb-toc alignnone” style=”display:none”><li class
   =”toc-level-1″ style=”margin-left:20px”>[A header goes here](https://wordpress.org/support/topic/summary-block-error-when-reloading-post/?output_format=md#advgb-toc-7de9f912-c695-473a-b600-166bbc985751)

   </div>
