Druid.scroll freezes if held in one place for a long time

[notbadgun]

Describe the bug
The "druid.scroll" freezes if held in one place for a long time, if the FRICT_HOLD is less than 0.5
The rest of the style settings are like this:

ANIM_SPEED = 0.2, -- gui.animation speed to point
BACK_SPEED = 0.35, -- Lerp speed of return to soft position
FRICT = 0.83, -- mult for free inert
FRICT_HOLD = 0.49, -- mult. for inert, while touching
INERT_THRESHOLD = 20, -- speed to stop inertion
INERT_SPEED = 70, -- koef. of inert speed
EXTRA_STRETCH_SIZE = 20, -- extra size in pixels outside of scroll (stretch effect)
POINTS_DEADZONE = 20, -- Speed to check points of interests in no_inertion mode
SCROLL_WHEEL_SPEED = 20,
SMALL_CONTENT_SCROLL = true, -- If true, content node with size less than view node size can be scrolled

To Reproduce
Set the style settings as above.
