Note : This is Windows OS specific issue and the same is not reproducible on Mac(10.12.6) and Linux(14.04 LTS) OS.

Thank you.

Adding RB Label as this is a recent Regression. Please remove if not required.
Thank You.

Cc'ing sky@ as well for inputs on this.

Still seeing the same issue on latest Canary-63.0.3230.0.

ellyjones / sky, please take a look as it is marked as stable blocker.

Thanks.!

Looking at this today.

Ah, I figured this one out I think.

The old code was:

ui::NativeTheme::ColorId text_color_id(bool has_focus, bool is_selected) {
  if (is_selected) {
    if (has_focus)
      return ui::NativeTheme::kColorId_TreeSelectedText;
    return ui::NativeTheme::kColorId_TreeSelectedTextUnfocused;
  }
  return ui::NativeTheme::kColorId_TreeText;
}

the new code is:

SkColor TreeViewDrawingProvider::GetTextColorForNode(TreeView* tree_view,
                                                     ui::TreeModelNode* node) {
  ui::NativeTheme::ColorId color_id = ui::NativeTheme::kColorId_TreeText;
  if (tree_view->GetSelectedNode() == node) {
    if (tree_view->HasFocus())
      color_id = ui::NativeTheme::kColorId_TreeSelectedText;
    color_id = ui::NativeTheme::kColorId_TreeSelectedTextUnfocused; // <---- bug
  }
  return tree_view->GetNativeTheme()->GetSystemColor(color_id);
}

which erroneously always sets the color to TreeSelectedTextUnfocused even when tree_view->HasFocus(), which doesn't do the right thing on Windows. Those colors are the same on Linux and Mac, which is why I didn't notice this earlier. Fix will be up shortly.

fix is up: https://chromium-review.googlesource.com/c/chromium/src/+/703095

views: use the right color for unfocused treeview selection

The existing code incorrectly always uses TreeSelectedTextUnfocused,
even when the TreeView is focused. Oops.

This should be fixed now, but I don't have a Windows machine to test it on, so please verify :)

Update : 
Retested above issue in latest chrome canary #63.0.3236.0 build on Windows(7,8,10) OS and issue is fixed. Now in 'Edit bookmark' dialog, selected folder's name is seen with white font color.
Kindly review an attached screen cast.

Thank you!
