Unexpected styling of a Button when used as PlotLabel

Question

Bug introduced in 8 or earlier and fixed in 11.3
_{Reported to the support as [CASE:3984748]}

Consider the following plot with a Button placed as PlotLabel:

ListLinePlot[Table[RandomReal[1, 1000], {i, 8}], PlotRange -> All, 
 PlotLabel -> Button["Press me!", Appearance -> None]]

After clicking the button and moving the mouse out it gets blue background:

(Note that this doesn't happen if the number of plotted points is substantially reduced: e.g., replace 1000 with 100 in the code above and you won't see this.)

How can I avoid this? I wish to have the default appearance after releasing the button.

Does basestyle/cachegraphics/false for plot help? - sent from Nokia 3310 — Kuba, Dec 19 '17 at 23:23
@Kuba Yes, BaseStyle -> {"CacheGraphics" -> False} solved the problem. You can post the answer and I'll accept it. — Alexey Popkov, Dec 19 '17 at 23:25

The fix is to add BaseStyle -> CacheGraphics -> False around:

ListLinePlot[
  Table[RandomReal[1, 1000], {i, 8}]
, PlotRange -> All
, PlotLabel -> Button["Press me!", Appearance -> None]
, BaseStyle -> CacheGraphics -> False
]

I would love to elaborate but this option is undocumented and the reason I knew it may be related is because I have faced similar issues:
