Dashboard cells off screen are not updated when variables change

Only cells visible on screen are reloaded for variable changes on dashboards. The way I've observed this is having multiple hosts reporting into a single bucket but I'd expect it to be the same when switching between buckets.

Steps to reproduce:

1. Install telegraf on two hosts and have them report in to a single bucket
2. Create a host variable of type query

import "influxdata/influxdb/schema"`

schema.tagValues(bucket: v.bucket, tag: "host")

3. Import the stock system dashboard from the template, add the following filter to two of the cells/graphs, drag one of them below the viewable area.
   |> filter(fn: (r) => r["host"] == v.host)
4. Change between the two host variables from the drop down and observe the two graphs by scrolling up and down

Expected behavior:
Both graphs to change which host is filtered to when the host variable is updated

Actual behavior:
Only the graph currently on the screen updates - the other is left filtering to the previous host
