Blockly update: dropdown fields on play sound effect block style bugs

[srietkerk]

There are two fields in the sound effect block when you expand all of its parameters that have dropdowns as values, effect and interpolation. The dropdowns for these fields do not have outlines on them, so they're a bit hard to see.

Also, when you click on the dropdowns, the list that you can select from appears at the top or bottom of the whole block rather than right next to the dropdown selector as it does in live.

To Reproduce Steps to reproduce the behavior:

1. Go to the blockly update target
2. Create a new project
3. Drag a play sound effect block into the on start block
4. Expand all of the parameters of the block
5. See the lack of outline on the dropdown parameters
6. Click on the dropdowns
7. See the menu on the bottom of the whole play block rather than right next to the dropdown
8. If you move the blocks to where there is no space to render anything underneath it, you'll see the dropdown items above the whole play block

These are screenshots of arcade, but I tested it to check and the same thing happens for micro:bit.

Expected behavior The dropdowns should be outlined like our other dropdown parameters and when you click on them, the menu should be close to the dropdown, just as it is in live.
