Upload Using Programmer does OTA upload instead when a network port is selected

[timkoers]

Using Arduino IDE 1.8.14 Hourly Build 2021/03/09 09:33, Windows 10 Pro x64

Steps to reproduce

1. Connect a board to your network that will produce a port under the Arduino IDE's Tools > Port > Network ports section. This could be an Arduino Yun, ESP8266 (info here), etc..
2. Select the network port from the Tools > Port menu.
3. Tools > Board > Arduino AVR Boards > Arduino Uno (or any arbitrary board)
4. Tools > Programmer > USBasp (or any arbitrary programmer that doesn't use a serial port). For the purpose of this demonstration it doesn't matter whether you actually have the programmer attached to the computer.
5. Sketch > Upload Using Programmer

The expected behavior is for the upload process to use the platform's program.pattern recipe. Instead, it uses the upload.network_pattern recipe. Resulting in an error like:

C:\Users\per\AppData\Local\Arduino15\packages\arduino\tools\arduinoOTA\1.3.0/bin/arduinoOTA -address 192.168.254.14 -port {upload.network.port} -sketch C:\Users\per\AppData\Local\Temp\arduino_build_374412/sketch_apr04a.ino.hex -upload {upload.network.endpoint_upload} -sync {upload.network.endpoint_sync} -reset {upload.network.endpoint_reset} -sync_exp {upload.network.sync_return} 
Resetting the board
Failed to reset the board, upload failed
An error occurred while uploading the sketch

The only way to get the expected behavior is by selecting an arbitrary serial port from the Tools > Port menu, which might not be possible if your computer doesn't happen to have a serial port.
