Flat UI llDialog too small

[canny]

With the Flat UI viewer, the llDialog window is smaller than before, so the string "————————————————————————————" doesn't fit in anymore (see attached screenshot). I would need to cut 4 characters for it to fit in basically all my scripts I am selling (3 would not be enough because of the line break). It would be good if the dialog window was wide enough for it to fit. This also happens on 4K with a UI scaling of 130% and a font DPI of 104, but the test below was done with default settings on Full HD, as you can see from Viewer Info.

Script:

default
{
    touch_start(integer total_number)
    {
        llDialog(llDetectedKey(0),"————————————————————————————\n TEST\n————————————————————————————", ["——————","🧡"], 56);
    }
}

The original bug report is more accurately "the em-dash character is wider in the Flat UI viewer which causes a particular string of them to wrap in llDialog" rather than "the llDialog is too small". The llDialog size did not decrease in the Flat UI viewer.
The question is, is this increase in llDialog width acceptable for other users of llDialog?

Width comparison.
