Content of first tab also shows at top of all subsequent tabs

This plugin has worked without problems for years, but recently the content of the first tab remained at the top of all subsequent tabs. Apparently the content div of the first tab will always have the classes “tab-pane in active”. This, combined with the !important declaration from assets/css/bootstrap-front.css, line 185:

.tab-content > .active {
  display: block !important;
}

overrides the element’s inline style of “display:none;”, making it always visible at the top of every tab.

I fixed this problem by editing the bootstrap-front.css file to remove the !important declaration. It doesn’t seem to have any ill-effects on the function of the tabs. I don’t know why, though, the first tab content should have the classes “in active”. Perhaps a problem introduced in a recent update?
