Some graphical elements are not disabled in setting panels when they should

[CyrilleB79]

Steps to reproduce:

1. Open braille setting panel
2. Uncheck "Show cursor"
3. Press Alt+F

Actual behavior:

At step 2, the edit field "Cursor blink rate (ms)" and the combo boxes "Cursor shape for focus:" and "Cursor shape for review:" are greyed out but not their associated label. For people with low vision, it is not so clear that these items are disabled.
At step 3, the focus movesto "Message timeout (sec)" field, whereas the acelerator key is alt+T, not alt+F.

Expected behavior:

At step 2., the labels should also be greyed out.
At step 3, the focus should not move since "Cursor shape for focus:" combo-box (having alt+f accelerator) is disabled.
