See: https://github.com/psifidotos/Latte-Dock/issues/823 Also applies to Icon-only Task Manager. .desktop files for WINE apps can be pinned, provided there are no spaces in the name. However, the icon acts only as a launcher and a separate icon appears for the task on launch. I thought including a StartupWMClass in the .desktop would work (in this case WINWORD.EXE) would work -- it doesn't. Is there a way of forcing the task icon and launcher icon to integrate? The task itself cannot be pinned. Using KDE Neon 5.12.5 with all updates installed as of 29th May 2018.
Support for Wine's quirks was recently overhauled (last week, in fact). The improved code will be in the next 5.12.x release as well as 5.13. Please try those and reopen if the problem persists (please pin anew).

Thanks for the follow up and pre-release testing, good to hear it works for you!
