Loophole in Add New Mapped Source lets users add two entries for one Source

[Megachile]

If you open a fresh Source Map tab, the Add New Mapped Source box won't let you select a source that is already mapped to the species you've selected. However, if you add sources to one species, then switch to a new one, the Add New Mapped Source box autofills with the last mapped source, which is great, but it does so even if the previously selected source is already mapped to the second gall, allowing you to create a second mapping of the same source to the same gall with potentially different text. The rest of the site seems to handle this fine so it's not a major problem, just noting it.
