User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0

Steps to reproduce:

Tab into a MathML object and a link.

Actual results:

The bounding box matched just one line of the MathML object (but not universally! some big ones do get full boxes) and a random box around the bottom of the link (but not universally! some links are fully boxed).

This happens on 128.6.0esr (64-bit) and 138.0a1 (2025-03-28) (64-bit).

Expected results:

87.0b9 (64-bit) correctly draws the binding box around where the thing is. Cf. video @ https://101010.pl/@nabijaczleweli/114241385096220321 [correct results seen around 0:22].
