Hi TAG,

This is an FYI about Chromium's planned implementation of the existing SVG2 side attribute on <textPath>.

During the Intent to Ship discussion, Blink API owners recommended notifying the TAG for awareness. We have already sent the Intent to Ship; apologies for the late notification. This issue is intended as an FYI rather than a request for a full design review, but feedback is welcome.

Feature summary

The side attribute controls which side of a path the text is placed on. Setting side="right" effectively reverses the path direction for text layout.

This allows authors to place text on the inside or outside of a shape, such as a circular path, without duplicating or manually reversing the path data.
