Incorrect phosphorus valence

[jblack-mestre]

Summary
When generating an .svg image with indigo-depict phosphorus_valence.cml, the phosphorus is incorrectly depicted as having a wrong valence of 5. It should have a valence of 3, with no added hydrogens.

Steps to Reproduce

1. indigo-depict.exe phosphorus_valence.cml phosphorus_valence.svg

Actual behavior
The phosphorus is depicted as having a valence of 5 with two added hydrogens.

Expected behavior
The phosphorus should be depicted as having a valence of 3 with no added hydrogens.

Environment details:

• windows 11
• indigo 4960b8e

Additional context
When adding sgroup bonds, indigo recalculates the valence and implicit hydrogens before it has removed the bond to the atom connecting to the sgroup. So P initially has a valence of 3, then this is raised to 4 when adding the bond to the new sgroup. Once the valence is recalculated, this is increased to 5.
