Expected / Desired Behavior / Question

People picker should be accessible to users when the control is used in a Teams application and the user is in high contrast mode

Observed Behavior

When teams is using high contrast mode the following behaviour is observed:

• The drop down area that shows a list of search results uses white text on a white background when the mouse hovers over one of the items
  

• When a user is selected the persona control within the people picker control shows white text on a white background

Steps to Reproduce

The issues was recreated by creating a new SPFX webpart with a single people picker control and deploying this to sharepoint and teams

Start with the People Picker control and reproduce the issue in a new SPFx web part deployed to SharePoint and Teams, with Teams high contrast mode enabled. Inspect the dropdown search-result hover state and the selected-user persona state. Done means both areas have readable foreground and background colors in high contrast mode.
