`@linear-gradient` macro broken in ternary operator

[levrik]

When using the @linear-gradient macro in the 2nd position of the ternary operator, just the first color value found is being used.

Rectangle { 
    background: true ? @linear-gradient(90deg, #fff 0%, #000 100%) : #000;
}

Rectangle { 
    background: false ? #000 : @linear-gradient(90deg, #fff 0%, #000 100%);
}

I simplified the code a lot for demonstration purposes.

These 2 codeblocks can be just copied into Window of https://slint-ui.com/releases/0.2.2/editor/ to reproduce.

I could work around by moving the gradients into a global and just reference it from inside the ternary operator. Looks like a bug in the parser to me.

Edit: Above statement isn't true. It's also not working when using a global.

Thanks for the report. Looks like the ternary operator always convert to the type of the first operand when both ways are possible.

Will look into it.

@ogoffart Ah, this makes sense. Thanks a lot! I've worked around by ensuring that the gradient always comes first for now.
