'rotate' attribute of the svg text element not implemented when used in combination with svg textpath element in some browsers

What type of issue is this?

Browser bug (a bug with a feature that may impact site compatibility)

What information was incorrect, unhelpful, or incomplete?

https://developer.mozilla.org/en-US/docs/Web/SVG/Element/text reports that the 'rotate' attribute of the 'text' element is fully supported by Chrome and Safari on IOS, but these browsers do not rotate text when combined with a 'textpath' element, whereas Chrome and Edge on Windows do perform the expected rotation. For the IOS browsers, even adding an additional 'tspan' element with rotation inside the 'textpath' element does not have the expected effect.

What browsers does this problem apply to, if applicable?

Chromium (Chrome, Edge 79+, Opera, Samsung Internet), Safari

What did you expect to see?

I expected that Chrome and Safari on IOS would rotate the characters of the text, as described by the SVG standard and exhibited by Chrome and Edge on Windows.

Did you test this? If so, how?

https://jsfiddle.net/k238fLus/1/

The above JSfiddle yields different output between the browsers in question at this time.

Start by reproducing the JSFiddle example across the browsers described, then compare the results with the SVG text, tspan, and textPath pages linked in the report. Determine whether the compatibility claim for svg.elements.text is incorrect and document the verified browser behavior in the relevant compatibility data.
