Describe the bug:
Clicking in the a heatmap visualization to apply filter nothing happens and a javascript error is thrown

Expected behavior:

Screenshots (if relevant):

Errors in browser console (if relevant):

TypeError: Cannot read property '$parent' of undefined

Any additional context:
Seems to be same issue as described for Pie Chart visualization in #25920, which is fixed at least in 6.5.3. But the issue iis still present for the Heatmap visualization in 6.5.3

cc @ppisljar could you have a look at that?

[ppisljar]

can't reproduce this on master

[larsflagan]

Tested this on 6.5.4 as well, and still the same issue.

Also noticed "malformed filter agg params, missing "query" on input - commons.bundle.js:3" on the browser console

Same issue here too on 6.5

@ppisljar @timroes the way to reproduce this is: create a heatmap with a split chart, a Y and a X axis. If you don't add the split chart, the heatmap works ok so I think that's the underlying issue.

@rayafratkina To reproduce this you need to use a histogram aggregation.

@rayafratkina You get the exact same problem with area/line/bar chart visualization (even in 6.5.4)
