Longstanding After Effects EXR Time Remapping / Freeze Frame Bug

A longstanding After Effects bug that has become incredibly frustrating and feels unacceptable in a professional workflow.

The issue affects EXR image sequences from 3D renders.

When I use Freeze Frame, or enable Time Remapping and set a Hold keyframe, After Effects shows the frame as frozen in the time-code for the footage. The Time Remap value stays constant and the hold keyframe is present, but the footage in the Composition viewer continues playing through the EXR sequence normally.

If I precompose the exact same EXR sequence and apply the freeze or time remapping to the precomp, it works correctly. So the issue appears to be with After Effects evaluating the EXR sequence directly.

This has been happening for a long time across multiple projects. Having to precompose every image sequence just to hold a frame is not a reasonable workaround.

EXR sequences are standard in professional 3D workflows, and Freeze Frame and Time Remapping are basic After Effects functions. They should work together reliably.

oh and its not a “purge cache / reset preferences / update GPU drivers” issue. 
Thanks!
