Send settings does not stick. (MicroPython)

[oddstr13]

In MicroPython mode, Send settings does not stick, and gets reset to "Dumb Mode" with 0ms line delay. This happens uppon hovering the "Select firmware -> MicroPython" checkbox/text, and after saving a file.

If I change the setting, and make sure not to hover "MicroPython" when changing to the scripts tab, I am able to upload a file, before the settings are reset and I have to change them again.

Could be related to #41, and magic happening there.

You can also clearly see #48 happening here, when hovering the Cancel button.
