Spoiler Shortcode bug? – Remove HTML Comments between Spoilers to fix

I have discovered a small bug in the Spoiler shortcode when using several spoilers in a row. I can easily work around it by not putting HTML comments in-between Spoilers, but I thought it might be representative of a larger issue, so I will share it in case it is useful for other reasons.
Here is the issue….
When using the Spoiler shortcode and stacking several of them together, I see a strange behavior.

1) Stacking them with no code between them works fine.
2) Stacking them with a generic HTML comment like this, is also fine.
[su_spoiler title=”Q1What is a comparable sale?”]
<p>Answer goes here….</p>
[/su_spoiler]
<!– generic html comment –>

[su_spoiler title=”Q2What is a comparable sale?”]
<p>Answer goes here….</p>
[/su_spoiler]
<!– generic html comment –>’

3) But if I put in this particular HTML comment (<!– wp:paragraph –>) in between Spoilers, it breaks the looping and gives me repeated entries. For example the code below gives me Spoilers Q4, 5, 3 4,5,2,3,4,5, then redisplays the entire page again with the correct sequence of 1,2,3,4,5.

Try pasting this code in and see what I mean. It does not seem to be Theme related. I can reproduce it on several of my sites. The

[su_spoiler title="Q1What is a comparable sale?"]
<p>Answer goes here....</p>
[/su_spoiler]
<!-- wp:paragraph -->

[su_spoiler title="Q2What is a comparable sale?"]
<p>Answer goes here....</p>
[/su_spoiler]
<!-- wp:paragraph -->

[su_spoiler title="Q3What is a comparable sale?"]
<p>Answer goes here....</p>
[/su_spoiler]
<!-- wp:paragraph -->

[su_spoiler title="Q4What is a comparable sale?"]
<p>Answer goes here....</p>
[/su_spoiler]
<!-- wp:paragraph -->

[su_spoiler title="Q5What is a comparable sale?"]
<p>Answer goes here....</p>
[/su_spoiler]

this particular comment was inserted by wordpress, probably visual editor or a gutenberg block, I did not create it originally, just copied it.
