Chart series reverses order after re-evaluating

Hey folks! While creating a columnChartField in a report we encountered a weird behaviour. While switching between different data sets, the chart series reverses its order (see attached picture). After some testing and reducing the expression we came up with the appended test case that reproduces this behaviour while picking "Case A" and "Case B" through the radio buttons. We further isolated the reason of the order-reversing behaviour and found it to be the dynamic component of the instructions in the column chart (see annotations in the code).
Is this behaviour expected?

This is the test case:

=load(
local!case: true,
a!dashboardLayout(
firstColumnContents: {

a!radioButtonField(
label: "Case",
choiceLabels: {"A", "B"},
choiceValues: {true, false},
value: local!case,
saveInto: local!case
),

a!columnChartField(
label: "Some chart",
/*instructions: "Case: "...
