Has anyone got known a technique/trick for overriding css style of the Office UI Fabric's component related to Spfx 1.4.0 (for the SP2019)?
More specifically I would like to update TextField red color border, when the validation fails. Update it to the color as in the default case - that correspond to the Peoplepicker style from the @pnp/spfx-controls-react. (The nice to have also would be to add the exclamation icon as before the validation error text.)
