....

The size of the front cavity is similar, but the articulation is very
different. The blade of the tongue is convex for [e] (or at least
it feels that way) but concave for [I]. The concavity enlarges the
front cavity, but the higher tongue position for [I] makes it
smaller, so the two articulatory adjustments going from [e] to [I]
can more or less cancel out, giving similar 2nd formant levels.
The difference in tongue configuration is parallel to that between
[s] and [S].
