Description

Reimporting a skeletal mesh causes "use high precision tangent basis" & "use full precision UVs" to reset and no longer being applied to the mesh.

Reported and tested in version 4.25.3(CL 13942748). Issue not occurring in versions 4.24.3(CL 11590370) and 4.23.1(CL 9631420). 

Steps to Reproduce
  1. Open a skeletal mesh in the content browser and switch to the mesh editor.
  2. Tick "use high precision tangent basis" & "use full precision UVs" in the build settings and hit apply changes.
  3. Right-click the asset in the content browser and select reimport.

Result: Build settings for "use high precision tangent basis" & "use full precision UVs" reset to unchecked and are not applied to the mesh anymore.

Expected:Build settings for "use high precision tangent basis" & "use full precision UVs" stay checked and are still applied to the mesh.
