`dx serve --always-on-top=false` is not working

**Problem**
`dx serve --always-on-top=false` is not working.

**Steps To Reproduce**

dx serve --hot-reload=true --nightly --arch=x64 --target=x86_64-unknown-linux-gnu --platform=linux --always-on-top=false

My program automatically opens.

Notice that it is always on top.

Click on `Help` Menu.

Click on `Float on Top (dev mode only)`.

Notice that it is now working as `--always-on-top=false` should.

**Expected behavior**

If I use `dx serve --always-on-top=false`, then I should not have to click on Help / `Float on Top (dev mode only)`.

**Environment:**
