What does this MR do?

These workarounds were in place due to #213324 (closed). Now that that's merged, these can be removed.

Screenshots

Before	After

Note that there's a slight change; this is acceptable, as now the Dependency List is using the default styling of GlTable (which thanks to #213324 (closed) is reasonable).
