Steps to Reproduce

1. Put on the canvas following SMILES:
   CC[C@H](C)[C@@H](C(=O)N[C@@H](C)C(=O)N[C@@H](Cc1c[nH]c2c1cccc2)C(=O)N[C@@H](CC(C)C)C(=O)N[C@@H](C(C)C)C(=O)N[C@@H](CCCNC(=N)N)C(=O)NCC(=O)N[C@@H](CCCNC(=N)N)C(=O)NCC(=O)O)NC(=O)[C@H](Cc3ccccc3)NC(=O)[C@H](CCC(=O)O)NC(=O)[C@H](CCCCNC(=O)COCCOCCNC(=O)COCCOCCNC(=O)CC[C@@H](C(=O)O)NC(=O)CCCCCCCCCCCCCCCCC(=O)O)NC(=O)[C@H](C)NC(=O)[C@H](C)NC(=O)[C@H](CCC(=O)N)NC(=O)CNC(=O)[C@H](CCC(=O)O)NC(=O)[C@H](CC(C)C)NC(=O)[C@H](Cc4ccc(cc4)O)NC(=O)[C@H](CO)NC(=O)[C@H](CO)NC(=O)[C@H](C(C)C)NC(=O)[C@H](CC(=O)O)NC(=O)[C@H](CO)NC(=O)[C@H]([C@@H](C)O)NC(=O)[C@H](Cc5ccccc5)NC(=O)[C@H]([C@@H](C)O)NC(=O)CNC(=O)[C@H](CCC(=O)O)NC(=O)C(C)(C)NC(=O)[C@H](Cc6cnc[nH]6)N
2. Press Add/Remove explicit hydrogens button to fold hydrogens
   

Actual behavior
System rise the spinner but it took too much time to got the result

Expected behavior
Folding hydrogens works same fast as unfold hydrogens.
Try it with following SMILES:
C([H])([H])([H])C([H])([H])[C@@]([H])([C@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@]([H])(N([H])C([C@@]([H])(N([H])C(C([H])([H])N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C([C@@]([H])(N([H])C(C([H])([H])N([H])C([C@@]([H])(N([H])C(C(N([H])C([C@]([H])(N([H])[H])C([H])([H])c1[n]([H])c([H])nc1[H])=O)(C([H])([H])[H])C([H])([H])[H])=O)C([H])([H])C([H])([H])C(O[H])=O)=O)=O)[C@]([H])(O[H])C([H])([H])[H])=O)C([H])([H])c1c([H])c([H])c([H])c([H])c1[H])=O)[C@]([H])(O[H])C([H])([H])[H])=O)C([H])([H])O[H])=O)C([H])([H])C(O[H])=O)=O)C([H])(C([H])([H])[H])C([H])([H])[H])=O)C([H])([H])O[H])=O)C([H])([H])O[H])=O)C([H])([H])c1c([H])c([H])c(O[H])c([H])c1[H])=O)C([H])([H])C([H])(C([H])([H])[H])C([H])([H])[H])=O)C([H])([H])C([H])([H])C(O[H])=O)=O)=O)C([H])([H])C([H])([H])C(N([H])[H])=O)=O)C([H])([H])[H])=O)C([H])([H])[H])=O)C([H])([H])C([H])([H])C([H])([H])C([H])([H])N([H])C(C([H])([H])OC([H])([H])C([H])([H])OC([H])([H])C([H])([H])N([H])C(C([H])([H])OC([H])([H])C([H])([H])OC([H])([H])C([H])([H])N([H])C(C([H])([H])C([H])([H])[C@]([H])(N([H])C(C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C([H])([H])C(O[H])=O)=O)C(O[H])=O)=O)=O)=O)=O)C([H])([H])C([H])([H])C(O[H])=O)=O)C([H])([H])c1c([H])c([H])c([H])c([H])c1[H])=O)C(N([H])[C@]([H])(C(N([H])[C@@]([H])(C(N([H])[C@]([H])(C(N([H])[C@]([H])(C(N([H])[C@]([H])(C(N([H])C([H])([H])C(N([H])[C@]([H])(C(N([H])C([H])([H])C(O[H])=O)=O)C([H])([H])C([H])([H])C([H])([H])N([H])/C(/N([H])[H])=N/[H])=O)=O)C([H])([H])C([H])([H])C([H])([H])N([H])/C(/N([H])[H])=N/[H])=O)C([H])(C([H])([H])[H])C([H])([H])[H])=O)C([H])([H])C([H])(C([H])([H])[H])C([H])([H])[H])=O)C([H])([H])c1c2c([H])c([H])c([H])c([H])c2[n]([H])c1[H])=O)C([H])([H])[H])=O)C([H])([H])[H]
