This suggests that trimmed asks will always keep appearing on custom themes, which is not true. I don't know whether it is no longer ever true or is now sometimes true.

Depending on that, I would suggest either

Trimming an ask from a thread may result in it appearing broken on some custom themes (i.e. [].tumblr.com).
To completely avoid issues with custom themes, leave the ask intact when trimming.

or e.g.

Trimming an ask from a thread has resulted in it appearing broken on custom themes (i.e. [].tumblr.com) in the past.
To completely avoid issues with custom themes, leave the ask intact when trimming.
