Import with New File option for Anim Sequences does not function

The "Reimport with New Source" functionality is currently not functioning in the Editor. When selecting the option with a clearly edited Anim, it is not updated. There is no message in the Output Log stating whether it was imported or not either.

Importing the new Anim as a brand new animation works without issues, but reimporting with a new source files does not currently work.

This happens with single and multi-frame animations. I tried with multiple FBX exporting formats and with the Aim_CC, Aim_RU, and Crouch_to_Stand_Rifle_Hip anims.

Video below showing the repro.

Repro Rate: 3/3

1. Open QAGame in the UE5 Editor
2. Search for an Anim Sequence (I used Crouch_to_Stand_Rifle_Hip) and open it
3. Export the Anim as an FBX (hit the button at the top of the Editor)
4. Import your Anim into Maya (or some other editor to edit the Anim)
5. Edit the joints in the Anim to be visually different than the original so you know it's edited (Make sure to key the frames so they remain in place)
6. Export the new Anim as an FBX
7. Back in the Engine, find the original Animation and right-click on it
8. Select "Reimport with New Source" and choose your newly edited Anim
9. Open the Anim Sequence once reimported

Result: Observe that the original Anim is not overwritten and does not change.

Expected: Animation are overwritten when reimported with a New Source.
