Bugzilla

#### Affected Versions:
Nightly 99.a1, Beta 98 and Release 97

#### Tested on:
MacOS 11
Windows 10

#### Preconditions:

  browser.search.region US
  extensions.formautofill.addresses.enabled - true
  extensions.formautofill.addresses.supported to "detect"
  extensions.formautofill.addresses.supportedCountries US,CA
  download latest Firefox Nightly with region locale
  have a complete address already saved in about:preferences#privacy

#### Steps to reproduce:

   1. Reach the address form on apple.com
   2. Using the autofill feature, select 1 saved address entry.
   3. Click in any auto-filled field in order to clear the form by using the autofill dropdown option.

#### Expected Results:

   1. Autofill should work accordingly after clearing the form using the "Clear Form" option.
   2. The preview should be compatible with the field placeholders without overlapping each other.

#### Actual Results:

    1. Autofill is no longer working after using the clear form option.
    2. Address autofill preview overlaps with field placeholder (see comment 1).

#### Notes:
Reproducible on Chrome: 1. No, 2. Yes
Please let me know if a separate bug is needed for the second issue (Address autofill preview overlaps with field placeholder) and I'll file a new one for that.
