Can't get a keyboard up in serial REPL

I'm trying a program with the ° symbol on android chrome. Serial is unresponsive i.e. my print statement isn't being echoed to serial window. I click the blue line click here or press CTRL c to enter REPL.
When i click on the cursor to get a keyboard so i can try CTRL+D (reboot) i can't get either of my keyboards to launch.

Android version 8.1.0
Samsung experience version 9.5
Chrome version 75.0.3770.101

Reproduza a interação com a REPL serial no Android 8.1 com o Chrome 75, usando o programa com símbolo de grau relatado e verificando tanto a abertura do teclado quanto o eco serial. Rastreie a entrada e o tratamento de foco da REPL serial no lado do navegador; está concluído quando o teclado abre e Ctrl+C/Ctrl+D ou a entrada digitada chega à REPL conforme esperado.
