LESS: .table-row-variant mixin doesn't respect @table-bg-hover variable

Created by: drewbeck

I've got @table-bg-hover set to a color in variables.less but my color isn't being respected!

It comes down to the following code. Note where the arrow is (<--------): the :hover is being set to a darker version of @table-bg-active instead of to @table-bg-hover!

tables.less:121:

.table-hover {
  > tbody > tr:hover {
    > td,
    > th {
      background-color: @table-bg-hover;
    }
  }
}

tables.less:158:

.table-row-variant(active; @table-bg-active);

mixins.less:441:

.table-row-variant(@state; @background) {

  ... snip ...
  // Hover states for `.table-hover`
  // Note: this is not available for cells or rows within `thead` or `tfoot`.
  .table-hover > tbody > tr {
    > td.@{state}:hover,
    > th.@{state}:hover,
    &.@{state}:hover > td,
    &.@{state}:hover > th {
      background-color: darken(@background, 5%);    <-----------
    }
  }
}
