Few UI issues

[tomusdrw]

1. Cancelling signing transaction in the extension doesn't enable the "Send" button back (same thing happens in case of any error, one need to change something to force re-calculation)
2. Race condition when typing amounts (can still press the button before the re-calculation kicks in).
3. Current transfer type can be de-selected (the UI goes into some weird state after that).
4. "Decoded" tab - copy icon jumps around (content is moving up/down - my suggestion would be to disable this completely and change the cursor to "arrow-plus").
5. Width of sender selector is changing (Marked as addressed in Apply behaviors and styles on Sender component. #270, but seems to still be there)
6. Internal transfer - receipt is incorrect (shows both networks - I guess it should be hidden anyway?).
7. After sending transaction, different receipt is displayed below and it initially seems to be missing payload.
8. When selecting the same account again - balance disappears.
9. Millau internal transfer doesn't work ("Transaction has a bad signature")

Just noticed this quirk as well:

The -> symbol is added and removed when switching between "Internal" and "Bridge" modes. It's visible after sending one internal transfer.

Niche catch. Addressed on #283

@tomusdrw Millau internal transfer doesn't work ("Transaction has a bad signature")

we agreed to not work on this correct?

Correct, it's an issue with the Chrome Extension not being able to use a custom hasher, so it's not something we could easily address.
