Password entry text misalignment

[DяA]

Package: lightdm-gtk-greeter
Version: 2.0.7
OS: Kali Linux 2020.1 (based on Debian testing)
GTK3 version: 3.24.14

When the greeter is configured to show both the user and the password entry, it is visible that the password field shows a higher left padding than the user one (see the picture attached).
Doing some tests in Glade shown that the property

<property name="primary_icon_activatable">False</property>

forces GTK to add an image at the beginning of the entry, thus adding some extra margin to the text. I've also spotted this behavior outside lightdm, where changing the primary_icon_activatable property of any entry to false adds the same image element, so I'm not sure if this is GTK's fault.

Anyway, I've preferred to fill the bug here just in case it can be easily fixed
