appdemon dashboard doesn't work on kindle anymore

[hatl]

What happened?

On Kindle Paperwhite Signature Edition (11th) Firmware version: 5.16.2.1.1

The label and the background color are visible. The icon doesn't show in the web browser and is therefore not clickable.

I've reduced the config to 1 item.

Version

4.4.2

Installation type

Home Assistant add-on

Relevant log output

No response

Relevant code in the app or config file that caused the issue

title: Hello Panel
widget_dimensions: [180, 180]
widget_margins: [5, 5]
columns: 4
scalable: False


layout:
    - wr_light

wr_light:
    widget_type: switch
    title: WR Light
    entity: light.licht

### Anything else?

I'm guessing some JS usage causes the issue.
Is there any way to debug this on the Kindle?
