Secret field initially hides input by making it invisible

When entering the secret into the entropy collection page, when initially entering it, the field is blank, after a moment the password dots appear.

As discussed in #120 it is a delay caused by the downloading of the font.

I think I understand the specifics: Firefox doesn't support the text-security-disc font. But the package we are using to get around this only discovers this when the font is supposed to be rendered.

So, Firefox only makes the request when the text box is selected which on my network takes ~300ms which is just enough to be (in)visible.

Closing as this seems to be an artifact of Firefox that we are just going to have to live with
