Short description of error
Viewport isn't updating Children hair particle when using any select tools.
Exact steps for others to reproduce the error
Create a object
Set on render panel on Hair to use Strip instead of Strand (if you are using eevee)
add hair particle ( I use only one hair particle)
add children simple (100) (any value still will show the issue)
On the view port change to particle edit
on the right panel (hotkey n) activate children for then to be displayed on the viewport.
to be able to select the strand set the selection mode to points (Top left corner)
If you grab any strand if any selective tool (no comb tool)
you will be able to move this main strand of the hair but children will stay frozen, unless you change the tool to comb and click in the viewport, then it will be updated.
Even if you delete the strand, the particles yet will be there until you change to any other tool and click on the viewport or if you go back to object mode.

Can confirm.
Undoing (even comb) will also keep the children in place...
(Pretty sure this has been reported before though, looking up the duplicate...)

Seen also in #65565 which lead to that "faux" bug report.
Note, in particular, @fclem closing comment on tagging.
A short video clip there illustrates the effect.

Hello, I'm still getting issues with Hair Children not being updating in viewport when in Particle Edit mode. Changing all the Children's setting like display amount or modifying clump curve are not reflecting in the viewport.
You need to turn ON and OFF Children option on Side Panel ( Tool / Options / Viewport Display / Children ) to be able seeing the update.
I've tested it on 2.80 official build and 2.81 alpha hash

@BintangPratama : this report was about the trransform.
For the settings issue, we have another open report, see #69000, so will close this again, lets continue discussion in #69000...
