bug#49963: 28.0.50; isearch failing in Dired after rectangle-mark-mode and query-replace

[laslydone]

  What happened:
In Dired isearch-{forward,backward} will no longer match anything after running
`rectangle-mark-mode' and `query-replace'.

  What I thought would happen:
In Dired after running `rectangle-mark-mode' and `query-replace',
isearch-{forward,backward} would match again.

  To reproduce:
1. emacs -Q
2. C-x d <RET>
3. C-x C-q
4. C-x <SPC> C-n
5. M-% <RET> <RET> (entering nothing)
6. ^s (searching for anything will show "Failing I-search: ANYTHING" in 
minibuffer)
