I recently updated from 8.2.1 to 8.2.6 and immediately noticed that on any data-tables that I have responsive: true enabled, even before the need for the responsive feature to kick in, all rows have the + icon. Usually, this icon only appears when responsive kicks in. I've tracked this down to an issue in the plugins.bundle.css file. I compared 8.2.6 with 8.2.1 and saw that there are some missing lines.

This is what is currently in 8.2.6 plugins.bundle.css

.dtr-control:before {
border: 0 !important;
height: 1.35rem;
width: 1.35rem;
line-height: 1.5;
text-indent: -999px !important;
margin-bottom: -0.3375rem;
margin-right: 0.675rem;
display: inline-block;
position: relative;
font-size: 1.05rem;
border: 0;
box-shadow: none;
mask-size: 85%;
-webkit-mask-size: 85%;
content: ' ';
}

Whereas in 8.2.1 it was

table.dataTable.dtr-inline.collapsed > tbody > tr > td.dtr-control:before,
table.dataTable.dtr-inline.collapsed > tbody > tr > th.dtr-control:before,
table.dataTable.dtr-column.collapsed > tbody > tr > td.dtr-control:before,
table.dataTable.dtr-column.collapsed > tbody > tr > th.dtr-control:before {
border: 0 !important;
height: 1.35rem;
width: 1.35rem;
line-height: 1.5;
text-indent: -999px !important;
margin-bottom: -0.3375rem;
margin-right: 0.675rem;
display: inline-block;
position: relative;
font-size: 1.05rem;
border: 0;
box-shadow: none;
mask-size: 85%;
-webkit-mask-size: 85%;
content: ' ';
}


By overwriting the 8.2.6 CSS class listing with what was previously there in 8.2.1 the bug goes away.

Can someone verify and validate this? And if it is the case can a patch be pushed to correct this? I hate the idea of needing to make changes to the plugins.bundle.css file. Usually, I would overwrite classes from metronic in my own CSS files if needing to change the default behavior, but this is one of those cases when overwriting doesn't seem to work.
