Re: [PATCH v9 0/6] MR1857: Draft: comdlg32: IFileDialog navigation bar

[Vladislav Timonin (＠vt)]

v8:
- simplify navbar positioning in dialog `update_layout`
v9:
- remove the (probably) unneeded `if` in crumb truncation logic
- use string length instead of size in `GetWindowTextW`
- call `MessageBox` with navbar handle, instead path edit handle
- move refresh/goto button width from dpi calculation in max crumbs width
