Switch / Buttons do not reset on sitemap

Hi guys,

I’ve not used openhab for my SamsungTV as remote for a while (last time on 3.4.x I assume), but I noticed, that my switch / button stays “pressed” and I need to refresh the sitemap to press it once again…
Could anybody reproduce and confirm on this? then I would create an issue on github.

Item:

String          SamsungTV_Key_Code                                    (gLivingRoomTV)                        {channel="samsungtv:tv:livingroom:keyCode", autoupdate="false"}

Sitemap:

Switch item=SamsungTV_Key_Code label="change channel" icon="movecontrol" mappings=[KEY_CHUP="+", KEY_CHDOWN="-"]

I can press it once (channel is switching) but now it stay’s “pressed” / on +.
Need to refresh the page (pull down), to be able to switch / press + once again.

Thanks!
