I tested the issue on Firefox Nightly 105.0a1 2022-08-21 by opening local and synced history items and observing the result.
When a local history website is accessed
{
"timestamp": 35426,
"category": "history",
"name": "opened_item",
"extra": {
"is_remote": "false"
}
When a synced history website is accessed
{
"timestamp": 11760,
"category": "history",
"name": "opened_item",
"extra": {
"is_remote": "true"
}
