Insorrect work with time and fs+ tag using "transform framerate" function

[B.F.]

If I export subtitles using "transform framerate" function, Aegisub remove "+" from "fs+"

before:
0,0:22:22.64,0:22:22.93,EdSong3_{0000,0000,0000}{move(343,11,332,17,0,288) (0,288,fs+21c&He98c543c0)}Spi

after:
0,0:22:42.42,0:22:42.71,EdSong3_{0000,0000,0000}{move(343,11,332,17,0,292) (0,292,fs21c&He98c543c0)}Spi

also if it "transforme framerate" in karaoke like this
Dialogue: 0,0:22:33.27,0:22:37.18,EdSong3_{0000,0000,0000}{ (0,1,alpha&HFF)}Spi{

(540,540,alpha&HFF)}der

it can replace " (0,1" with " (0,0" and broke the animation
Dialogue: 0,0:22:22.64,0:22:26.42,EdSong3_{0000,0000,0000}{ (0,0,alpha&HFF)}Spi{

(493,493,alpha&HFF)}der

(In [3838]) Add \fs+ and \fs- to the ASS parser so they aren't killed by transforms. Updates #1007.

(In [3839]) Prevent times from rounding to the magic zero in the framerate transform. Updates #1007.

(In [3840]) Merge framerate transform fixes in r3838-r3839 from trunk. Closes #1007.

Check fixes on r3974 beta.
"Transform framerate" filter now work without problems.
Thanks.

P.S.
Beta is still crash sometimes, but I hope final version will be stable.

Can we double check this to make sure it's really fixed?

[B.F.]

It fixed.
Re-check on the 2 different scripts, and found no problem in r3974.
Both broke if i export them in the 2.1.7.

doh, I took the 'still crash sometimes' as related to this bug, but it was meant to be 'in general'. Closing as fixed.
