Images exported from grid (in bulk) while selecting custom dimension have wrong size and no quality
Lightroom for iPad, v9.5.1 / iPad Pro 12.9 6th Gen / iOS: 18.1
Reproduction path:
* Edit a particular image and export it with custom dimension of 4000px.
* Export said image.
* See that size is 4000x3200 and quality is as expected
* Click "g" to go back to grid.
* Select that image on the grid as you'd do to do a multiple image export
* Select the exact same settings, custom dimension of 4000px
* See that the output is 4000x3199px and the quality is crap
This happens for multiple pictures regardless of format type (tested AVIF and JPG)
