Reordering inserts at the wrong position when the store is filtered.

Usecase:
From the example where we have Staff, replace staff with product of a production/assembly line, the order/index of row is actually priority of that product, sometimes reordering of product is required, for which we would filter on product list, and than re-prioritize the order inside a schedule.

Suppose in a factory you have 10 bikes(bicycles) of different types to be assembled/tested; it cannot be done for all 10 simultaneously, so prioritizing is required, and also re-prioritizing with applied filters is required

Steps to Repro:
Load filtering demo https://www.bryntum.com/examples/scheduler/filtering/
In features activate row reorder

features : {
        filterBar  : true,
        stripe     : true,
        timeRanges : true,
        rowReorder : true,
        eventEdit  : {
            items : { ...
 

Put i in staff filter, you will see

Staff	Role
Linda	Core Developer
Henrik	Sales
Maxim	Developer & UX
Mike	CEO
Gloria	CEO

Now drag Gloria and drop between row 1 and 2 (Linda and Henrik)
When you try dropping first time you want see any change, it looks like nothing worked
Try repeating step 4 again, you will notice, instead of Gloria getting reordered, Mike is disappeared

Staff	Role
Linda	Core Developer
Henrik	Sales
Maxim	Developer & UX
Gloria	CEO

Now try moving, Linda between Maxim and Gloria
You may notice instead of moving there, Linda is at the bottom

Staff	Role
Henrik	Sales
Maxim	Developer & UX
Gloria	CEO
Linda	Core Developer

You can remove the filter and see there very few row remaining, only 4 are there instead of 7

You may not find the weirdness(random reordering), as exactly as mentioned here, but you will notice it.
