Only reconnect if WiFi updated

[presslab-us]

If only the parameters have been updated then don't try to reconnect on save. Otherwise _ssid and _pass are blank (because "placeholder" input attribute is used) and the connection will fail.

still a problem in the latest code

What browser? placeholders should not be submitted in inputs

[presslab-us]

Yes, exactly, the placeholder is not submitted, and therefore WiFiManager uses the returned (blank) SSID and password to reconnect. This causes the connection to fail.

My patch makes it so that if the SSID and password are not changed it will not try to reconnect with blank _ssid and _pass.

Tested with Chromium 110.0.5481.177

If its blank then it shouldnt be connecting at all

[presslab-us]

Is that the intended behavior? Every time that you go into the settings page you need to type in the ssid and password again, even if the placeholder is correct?

No, I will take a look, something else seems to be broken also
