The failure has been bisected to this commit:

commit 1b331ae505e63033634d9f5267ca1949336f75d8
Author: Kristian H. Kristensen <hoegsberg@chromium.org>
Date:   Mon Nov 5 21:19:21 2018 -0800

    mesa: Add core support for EXT_multisampled_render_to_texture{,2}

    This also turns on EXT_multisampled_render_to_texture which is a
    subset of EXT_multisampled_render_to_texture2, allowing only
    COLOR_ATTACHMENT0.
