[2.0.73] X marks from right clicking ingredients after recipe change disappear when re-loading machine view

[reduke]

When using filtered inserters and hence having to mark old ingredients for bot removal upon recipe change in assembling machines, the ingredients are marked with a red X correctly.

When closing the viewport of that machine and then going back into it, the red X is no longer visible. If you right click the slot again nothing appears to happen, when in actuality you have cancelled the removal request. Right clicking a third time makes the red X show up again, but only until you close and re-open the machine viewport.
