Code folding triangles don't update on unfold when block above them is removed

[jwestbrook]

Scenario :

In a PHP file with mixed HTML and PHP I'm folding the <tr>s of a table. If I have a set of 3 rows and I unfold row 2 which has 2 PHP blocks within it, and remove one of the blocks, then go to row 3 to unfold - the row will unfold but the triangle will not update and I think the folded state will not save.

For example

Step 1

<table>
<tr>...</tr>
<tr>...</tr>
<tr>...</tr>
</table>

Step 2

<table>
<tr>...</tr>
<tr>
    <td>
       <?php
       if($variable)
       {
           foreach($variable as $v)
           {

           }
       }
       ?>
   </td>
</tr>
<tr>...</tr>
</table>

Step 3

<table>
<tr>...</tr>
<tr>
    <td>
       <?php
       if($variable) //remove
       {                  //remove
           foreach($variable as $v)
           {

           }
       }             //remove
       ?>
   </td>
</tr>
<tr>...</tr>
</table>

Step 4

<table>
<tr>...</tr>
<tr>
    <td>
       <?php
           foreach($variable as $v)
           {

           }
       ?>
   </td>
</tr>
<tr>...</tr>
</table>

At this point unfolding row 3 will show the code contained, but the triangle will not rotate and will not respond to any more clicks unless you reload Brackets.

Don't know if its worked before

I've attempted this with and without extensions enabled.

No errors logged in console

@jwestbrook thanks for this. I'm able to reproduce this with some small variations on your test.
I am fairly sure this is related to #12232

Yep that looks like the same behavior I get - glad I could illustrate a test case

Should be fixed in 1.8 by #12521
