`x-show-tip` not display propertize text string, is this expected?

[Eval EXEC]

Hello,

I want to use `x-show-tip` to show some colorful text to tooltip. But it seems that emacs doesn't make the tooltip text colorful.

I can reproduce it by eval this _expression_:

```elisp

(x-show-tip
  (propertize "hello emacs" 'face '(:foreground "red"))
  nil nil 2 0 0)
```

I expect above elisp _expression_ should make a tooltip to display red text,

 but it displayed white foreground text actualy.

This can be reproduced on master branch:

```
