On the Understanding page for 1.3.5 Identify Input Purpose, the link to 'Input Purposes for user interface components section' is broken and does not do anything.
The link's current destination is: https://www.w3.org/WAI/WCAG21/Understanding/identify-input-purpose#input-purposes
I believe the link's destination should be: https://www.w3.org/TR/WCAG21/#input-purposes
This appears to have been broken since the look and feel of the understanding pages was updated in late 2022.
