iOs - button with ImageSource - defined heightRequest - ImageSource is not shown

[rokmeglic71]

I have two buttons.

The first one have heightRequest defined.

<Button               
    HeightRequest="15"
    ImageSource="j_wifi.png"
    Text="test"
    Clicked="Button_Clicked_1"/>

The second button have no heightRequest defined.

<Button                 
            ImageSource="j_wifi.png"
            Text="test"
            Clicked="Button_Clicked_1"/>

The first button does not shown the icon.
Icon is larger then 15.

Result?

Notices:
When I re-asign the same icon imageSource on click handler, it works

... but only until the page is re-rendered. For example, when I click on the second button, the first button imageSource disappears.

Platform specific?
Android - it works.
iOs - it does not work if heightRequest is defined.

I tested with smaller images, so heightRequest is larger then image size, still does not work.

When I tested further I can see a small image inside the button.
Looks like setting heightRequest on button, does affect on resizing of the image inside the button.

This small image inside the button appears when the HeightRequest="24" has equal or greater value of the picture (24 x 24).
If I increase the HeightRequest to 35, the inside image is getting bigger, but still not the same as on the button which has no heightRequest attribute defined.

This resizing ends when the HeightRequest="43" - ImageSource=24 = 19 device units diference.
So when there is 19 units diference, the internal resizing of image stops, at least seeing with my inperfect eye:)

P.S: CoPilot gave me great help with code examples to isolate this issue.
