+Previously, in the TinyMCE AI Chat panel, source tags displayed in the response area could appear in rows of only two instead of three on certain browser and operating system combinations. The `max-width` of the source tags did not account for the additional space consumed by thicker scrollbars on some platforms, causing the third tag to wrap to the next row.
