Query params from link-to destination wiped out if the current URL has a different query param

Hi all,

I'm experiencing an issue where I have a link-to specifying a particular query param with its destination, like so: `{{#link-to "foo.bar" (query-params baz=true)}}`. This link-to is on route `my-route` with a _different_ query param (URL has "my-route?creating=true"). When I click that link-to, I am successfully taken to `foo.bar`, but my query param of `baz=true` seems to be wiped out.

I can get around this by adding "baz" to the query params on the controller for "my-route" like so: `queryParams: ['creating', 'baz']`, but this seems like a band-aid fix to a larger problem. And it doesn't entirely make sense because `baz` is not relevant to "my-route".

My team's project is currently on version 2.18 of Ember. I've looked around for other similar issues posted here but could not find anything. Apologies if there is one that I missed somewhere.

Thanks!
