XYZ Tiles missing in QGIS 3.2

Although it doesn't appear in the "Add Layer" dialog, I can add XYZ tiles from this option in the "Browser" panel:

Right-click to add a new tile server connection, or choose one of the existing ones.

If you don't have a "Browser" panel open, use View... Panels... Browser to get one.

The suggestion that you can get the XYZ Tiles from the "Browser" Panel is misleading since there is no panel named Browser in QGIS 3. The only way to get this option is to open the "Add Layer" window and select the 'Browser' tab from there.

Where the browse button is in the QGIS 3.4 Data Source Manager
