I'm only guessing but is it some type of biscuit joint?
Nice work with the boxes, especially the stained glass, an art in itself.
Mitre joints are rather weak if just glued, especially if the glue surface is small and the strain on the part varies, as in a door or lid. Oily exotic timbers are even less gluable. Some form of reinforcement of the joint is needed. As you will know there are various kinds, including wee right-angle nails (used in picture frames a lot) with some reinforcements "honest" (can be seen) and others hidden in the joint.
Very small mitres are difficult to biscuit as the biscuits are generally too long so show on the inside or outside corner - perhaps both. The Festool Domino tool - a cross between a biscuit joiner and a mortiser - allows the insertion of very teeny internal dominoes (loose tenons) that are a third or quarter as wide as a biscuit. They act in the same way - a small internal mortise & tenon joint to keep the edges of the mitre joint together with proper long grain to long grain glue faces. The ones in that door are 20mm long by 4mm thick by 12mm wide.

If you haven't used a Festool Domino machine I recommend finding somewhere to have a go on one. They are tremendously versatile and will make all sorts of mortise & tenon style joints with precision and speed. The machine can be used to make the initial (accurate) mortise that one then expands or reshapes by hand to use hand-made tenons, such as through and/or wedged tenons.
I've tried (and sort of suceeded) to make all hand-made mortise and tenon joints but it takes a tremendous amount of time if one is relatively unpracticed; and can easily go badly wrong, wasting a workpiece. Such skills need that 5 year apprenticeship where one makes 100 poor ones before getting the skill to make a thousand proper ones, in less than a day each.

The stained glass is not quite right yet, especially the soldering - another skill needing many man-hours of practice before one gets neat and regular solder lines of the required width. I suspect that I need a lot of refinement also in my aesthetic sense before the designs look better than just juxtaposed dollops of coloured glass.
