Multiple `${query[[]]}` expressions on the same page produce random `(empty table)` results

[rc042]

Version: SilverBullet v2

Description

When a page contains multiple ${query[[]]} expressions, some of them randomly render as (empty table) even though the same query works correctly when alone on the page.

The behavior is non-deterministic: on the same page, sometimes query 1 renders correctly and query 2 is empty, sometimes both render, sometimes both are empty.

Minimal reproducible example:

Page frontmatter:

---
week: 16
year: 2026
---

Test 1 — same alias t on both queries:

${query[[
  from t = index.tag("task")
  where not t.done
  and t.week == _CTX.currentPage.week
  and t.year == _CTX.currentPage.year
  and string.startsWith(t.page, "Journal/Projet/Alpha/2026/")
]]}

${query[[
  from t = index.tag("task")
  where not t.done
  and t.week == _CTX.currentPage.week
  and t.year == _CTX.currentPage.year
  and string.startsWith(t.page, "Journal/Projet/Alpha/2026/")
]]}

Result: Random — sometimes both display, sometimes one or both show (empty table).

---

Test 2 — distinct aliases t1 and t2:

${query[[
  from t1 = index.tag("task")
  where not t1.done
  and t1.week == _CTX.currentPage.week
  and t1.year == _CTX.currentPage.year
  and string.startsWith(t1.page, "Journal/Projet/Alpha/2026/")
]]}

${query[[
  from t2 = index.tag("task")
  where not t2.done
  and t2.week == _CTX.currentPage.week
  and t2.year == _CTX.currentPage.year
  and string.startsWith(t2.page, "Journal/Projet/Alpha/2026/")
]]}

Result: Same random behavior — distinct aliases do not fix the issue.

---

Test 3 — implicit _ variable (no alias):

${query[[
  from index.tag("task")
  where not _.done
  and _.week == _CTX.currentPage.week
  and _.year == _CTX.currentPage.year
  and string.startsWith(_.page, "Journal/Projet/Alpha/2026/")
]]}

${query[[
  from index.tag("task")
  where not _.done
  and _.week == _CTX.currentPage.week
  and _.year == _CTX.currentPage.year
  and string.startsWith(_.page, "Journal/Projet/Alpha/2026/")
]]}

Result: Same random behavior — using _ does not fix the issue either.
