--- Comment #1 from Magnus Aagaard Sørensen <***@aagaardsorensen.dk> ---
Steps taken to triage:

A: With taps
* Set Okular to open files in tabs
* Open file1.pdf and file2.pdf
* Ensure no file has trim enabled
* Trim margins on file1 with View -> Trim View -> Trim Margins
* Observe trim as expected, switch to second tab with file2
* Trim margins on file2 with View -> Trim View -> Trim Margins
* Observe no trim
* Switch to first tab with file1
* Unselect trim margins
* Observe file is still trimmed

B: With windows
* Set okular to not open files in tabs
* Open file1.pdf and file2.pdf
* Ensure no file has trim enabled
* Trim margins on file1 with View -> Trim View -> Trim Margins
* Observe trim as expected, switch to second window with file2
* Trim margins on file2 with View -> Trim View -> Trim Margins
* Observe no trim
* Switch to first window with file1
* Unselect trim margins
* Observe file is still trimmed

In both cases, to re-enable the trim feature, is must be deselected in all open
files, and the file which is still trimmed, where it ought to be in default
mode, can be returned to the default view by selecting trim margins, and then
deselecting it again.

I'm not the developer, updating as part of the Okular Bug Day for the Bugsquad.
