Handsontable version 6.2.2
I have a problem like this issue https://github.com/handsontable/handsontable/issues/5685
The problem is when I reopen jQuery Dialog handsontable header disappear but when I click the table again, scroll the table or scroll the dialog, the header will come back.
I found that one css property cause the problem.
.handsontable .ht_clone_left thead, .handsontable .ht_master thead, .handsontable .ht_master tr th {
visibility: hidden;
}
It will not cause the problem but also cause the problem if the table is scrollable.
Thank you in advance
