Setting button transparency dynamically triggers error

[DavidPROVOST]

I tried new button dynamic color feature.

I use a measure to set button fill color. Whenever measure result is a usual 6 digits hexa code, it works fine. But when result is "FFFFFF00", which stands for "transparent", I get an error message "an error occurred while rendering the report".

I'm using Power BI desktop (Version: 2.82.5858.641 64-bit).

I raised ticket about this, but MS support tols me this place is the one to declare bugs...
