Upload settings in boards.txt not being honored

[naigonakoii]

I'm using an Adafruit Feather 32u4. Upload fails through VS Code for this board (build is fine). It works perfectly in the Arduino IDE.

I believe this issue is that there are custom upload settings specified in the boards.txt for this board (taken from boards.txt installed in the adafruit AVR official package):

feather32u4.upload.protocol=avr109
feather32u4.upload.maximum_size=28672
feather32u4.upload.speed=57600
feather32u4.upload.disable_flushing=true
feather32u4.upload.use_1200bps_touch=true
feather32u4.upload.wait_for_upload_port=true
feather32u4.upload.tool=arduino:avrdude

However, from my debugging the Arduino plugin for VS code does nothing with these settings, and as such the upload fails. Specifically, I believe the speed and the wait_for_upload_port are the two critical ones that prevent the Feather from resetting properly before the upload begins which causes the failure.

If there is a manual workaround for this issue (ie something I could put in the arduino.json file in the "configruation" entry) please let me know as that would be okay as well.
