Gluing cross-braces of a Windsor chair back into the legs

I have a wooden chair with four legs that fit into the seat, with front and
back legs on each side held from splaying out by a fore-and-aft cross-brace;
those two braces are themselves joined by a side-to-side brace. On one side,
the braces have come loose from the holes in the legs, making the chair
rickety. I tried gluing them with PVA glue but the glue joint broke almost
immediately (after letting it set for several hours).
I don't want to have to unglue and re-glue any of the other joints (in case
I make things worse). What is the best glue to use for sticking a joint
where one wooden piece fits into a hole in the side of another? I can
extract the cross-brace by about 10 mm, but there isn't enough play to
remove the brace totally to line the hole with glue, so I have to rely on
straining the joints to expose as much of the ends of the brace, smearing
glue around the exposed part of the brace (at both ends) and then pushing it
back together.
I would get it all steam-damp with hot water and pull apart all the leg joints, then reassemble using traditional glue (which is plant based now not animal based). I'd use spanish windlasses to bind it together while the glue sets. Using old fashioned glue like this means that there is no need to get every last smidgeon of original glue out because it will be bound in when the new hot glue goes in.
But whatever glue you use, remember to have the chair standing on a good flat floor (or use a flat board if the chair is upside down) as you glue it so the four legs will touch the floor properly.
I'm interested in your remarks about traditional glue. I've been using
hot hide glue for decades now and - probably because I still have a
mountain of pearls in stock and haven't needed to buy any for ages - I
hadn't noticed that it's plant-based now.
What's it like to use? Does it have the same/similar properties as hide
glue eg, self-clamping and adhesive properties that vary according to
dilution? Does it keep as well or better? I know when not to reheat a
pot "one more time" and wondered if the vegetable glue gives off the
same sorts of clues about its condition.
Thanks,
Nick
