Slice editor has issues with stored queries

[mechanarchy]

The slice editor does not load stored queries properly, as it omits the trailing quote mark. My beancount file contains these lines (line numbers included for context):

   155	
   156	2021-01-01 query "Assets over time" "
   157	  SELECT date, LAST(balance)
   158	  FROM OPEN ON 2021-07-01
   159	  WHERE account_sortkey(account) ~ '[0]'
   160	"
   161	
   162	2021-01-01 query "Debt over time" "
   163	  SELECT date, NEG(LAST(balance))
   164	  FROM OPEN ON 2021-07-01
   165	  WHERE account_sortkey(account) ~ '[1]'
   166	"
   167	

When I load Fava and go to the journal view, then click on the date for one of these entries, the trailing quote is removed:

Suspected problem location

fava/src/fava/core/file.py

Lines 238 to 239 in 516704a

	if not line.strip() or re.match(r"\S", line[0]):
	return entry_lines
