"Split to here" doesn't appear on posts loaded when scrolling

[matteocontrini]

Steps to reproduce:

• Open a large discussion with many posts
• Click "Split from here" on one of the first posts
• Scroll down until new posts are dynamically loaded
• Notice that the new posts that were loaded don't have the "Split to here" button

Screenshot (the button is missing after a certain post):

Affected by this as well

If you go into the web debugger you can find this section in the post

<button class="flagrow-split-endSplitButton Button Button--link hasIcon" style="display: none;" type="button" title="Split to here"><i class="icon fas fa-code-branch Button-icon"></i><span class="Button-label">Split to here</span></button>

If you remove style="display: none;" (this is css to remove a element) it will appear and function normally, as far as I know.
Successfully split 50 posts this way.
