Clang: Highlighting and Navigation broken due to precompiled header

I don't know the exact steps to reproduce, but I have seen it a couple of times.

When it happens, Ctrl+Left Click navigation is broken, however F2 on a symbol still works. The "symbol chooser" just shows <no symbols>.

I didn't find a possibility to force a re-parsing, however after taking the screenshow and while writing this report, I tested F2 again and suddenly highlighting came back.

The info bar already tells what's wrong, however it does not tell what can be done to recover from this situation. If deleting the file would help, a button to trigger that would be nice.
