In Firefox 89.0 multiple sticky elements disappears without a reason.
Here is an example (usage of position: sticky):
<table>
<tr style="position: sticky; top: 0px; height: 30px;"></tr>
<tr style="position: sticky; top: 30px; height: 30px;"></tr>
<tr style="position: sticky; top: 60px; height: 30px;"></tr>
<tr style="position: sticky; top: 90px; height: 30px;"></tr>
...
</table>

Just scroll down and hover wild over sticky elements.
Are there some CSS styles or JavaScript missing, or is this just a weird browser bug? In Chrome everything seems fine.
Additional note: Solution should work with table markup and should work with multiple columns.
