Provide a source, I have never come across anything even remotely suggesting the above.
From red star publications (Gordon & Khazanov)
The air craft would run away in a dive to the extent that pilots had to hold it back, because its good aerodynamic qualities made it easy to exceed the IAS of 650km/h(404mph) which was dangerous due to insufficient structural strength.

The two main plants producing Yak3's were Saratov and Tbilisi.
Saratov machines consistantly had problems gluing the under wing skinning to the spar ribs. This was investigated and found to be due to incorrect manufacturing procedures. 114 Yak3's were grounded until the variuos field mods could be iincorporated. Which seems to have taken up the last few months of 44.
Tbilisi produced Yak3's do not seem to have sufferred this. indeed they were heavier than the Saratov version by typically 25kg but faster by typically some 15km/h at level speed.
IMO the Yak3 would continue to accell in a dive and AH should not allow this to go on without penalty. I would expect to hear fuselage groans at 410 follwed by wing break up at approx 430> 450 depending upon G loading.
High speed pursuit is no what this ac was about...............its a furballer
