API doc(.html) generated using this stylesheet.css didn't had overflow: auto applied from .summary-table > div element but overflow been applied from .col-first, .col-second, .col-constructor-name which caused our achecker failure. .summary-table doesn't have affect.

Please find the below stylesheet.css used in one of our javadoc generated failed API doc

.summary-table > div, .details-table > div {
    text-align:left;
    padding: 8px 3px 3px 7px;
}
.col-first, .col-second, .col-last, .col-constructor-name, .col-summary-item-name {
    vertical-align:top;
    padding-right:0;
    padding-top:8px;
    padding-bottom:3px;
}
.table-header {
    background:#dee3e9;
    font-weight: bold;
}
.col-first, .col-first {
    font-size:13px;
}
.col-second, .col-second, .col-last, .col-constructor-name, .col-summary-item-name, .col-last {
    font-size:13px;
}
.col-first, .col-second, .col-constructor-name {
    vertical-align:top;
    overflow: auto;
}
