Keyboard layout resets to the previous one after wrong password message disappears on lock screen

[Dzmitry Petukhou]

**Summary:**
Keyboard layout resets to the previous one after wrong password message disappears on lock screen.

**Steps to reproduce:**
1. Lock the screen.
2. Type an incorrect password while using Keyboard Layout A.
3. A small warning message appears under the password input.
4. While that message is still visible, switch to Keyboard Layout B.
5. Wait until the message disappears.
6. Observe: the keyboard layout automatically reverts to Layout A.

**Expected result:**
The chosen keyboard layout (Layout B) should remain active after the message disappears.

**Actual result:**
When the warning message disappears, the layout resets to the one active before switching.
