The highlighted part in important. Why would the pilots of fighters know that the shields don't work in subspace unless they had a reason to use it. Chasing ships through the node may never have been done before, but battles in subspace do appear to have happened. Or at the very least, they either expected that it would happen or planned for such an event. In any case, it was researched enough that even the pilots were informed of this fact.
Check the ref bible; it states that

The camera shows a medium shot of the two scientists at the terminal, standing near a small enclosed test area. Energy & light flickers from inside the test enclosure.

TerranSci-1: You see from this part of the captured ship breakdown the energy flow is constant.
VasudanSci-1: Yes…but how do you explain what happens during a jump? It doesn’t seem as if the rate is sufficient to support the required level.
TerranSci-1: Very good observation “EEEEE” You live up to your credentials. You see…
[walking to another monitor]
The Terran gets out of his chair and the Vasudan follows him over to the research equipment where the other scientists are tweaking things.[possibly cut this part if we don’t want to show more scientists]

TerranSci-1: We’ve been able to get a prototype shield system working under normal conditions. However when we simulate jump phenomena there’s no way to keep the power levels high enough.
VasudanSci-1: But under normal conditions the shields actually protect the inside structures?
[cut to show both scientists]
TerranSci-1: Correct. They stop almost all damage from getting through, at the cost of energy, which explains how the Shivan ships have been able to defend against our attacks so easily. Despite its shortcomings in subspace, we should be able to start producing shield systems for use on our ships.

There is (somewhere) a mention that destroying a ship in subspace can destroy a node, however this doesn't imply in-subspace combat... if blockades were in operation during the TV war (as I think they were), a ship could conceivably be blown up before exiting subspace completely... maybe even explaining the missing Talnia system?
