Bug report

ComboBox with filtering option set to "contains".

Search for the last element in ComboBox dropdown and select it. Delete the selected item with mouse selection and "Delete" button. The dropdown will open again. Select the first element in the dropdown. It will close and no data will be selected. If we repeat the scenario and instead of selecting the first element, we select another one, everything is working properly.

This is regression introduced in 2018 R1 SP1

Reproduction of the problem

  1. Open this Dojo and run it
  2. Select the ComboBox and enter "rib", then select "Rib Knit"
  3. Unfocus the ComboBox and then focus it again
  4. Using the mouse select the "Rib Knit" text and delete it. The dropdown of the ComboBox will open.
  5. Select the first element "Cotton".
  6. The dropdown closes and no item is selected

Current behavior

Please check this demo video.

I notice that some of the styling has changed for the Blue Opal theme in the latest release (2019 R1), notably the background colour of the selected page on the grid and the already selected items on a Drop Down List have gone from dark blue to a bright blue (see attached screenshots from

Is this by design or by mistake?

Particularly on the drop down list, this change makes it more difficult to identify the already selected items.

Can this go back to what it used to be - or is there a way of manually changing this setting via the site.css?
