UI can end up in strange state where subreadings of previous analysis are shown

[unhammer]

1. open https://beta.apertium.org/index.nno.html#analysis?aLang=nno&aQ=
2. type in grapsripsforbetring and analyse
3. type kakene and analyse

Developer tools says only kakene is sent
curl 'https://beta.apertium.org/apy/analyze' -X POST -H blah:blah --data-raw 'lang=nno&q=kakene'
and only the right analysis is received

[
	[
		"kakene/kake<n><f><pl><def>",
		"kakene"
