1258571 - Markup doesn't display anything after using "Search HTML" on different pages in tab history

Status: RESOLVED WORKSFORME

(DevTools :: Inspector, defect, P2)

Description

[arni2033]

>>>   My Info:   Win7_64, Nightly 48, 32bit, ID 20160320030409
STR:

1. Open the following "data:" url in a new tab
data:text/html,<div class="b_element"><span class="no_element">before</span></div><style>.b_element::before{content:"_span_"}

2. Paste the following "data:" url into urlbar in the tab from Step 1 and press Enter
data:text/html,<div class="b_element"><span class="no_element"></span></div><style>.b_element::before{content:"_span_"}

3. Open inspector, type "element" in the field "Search HTML"
4. Press Enter 3 times (with pauses ~2s just in case)
5. Press Alt+Left to go back in the tab history (-1)
 [make sure that "Search HTML" field is still focused and has the same value - "element"]
6. Press Enter 3 times (with pauses ~2s just in case)
7. Press Alt+Right to go forth in tab history (+1)

AR:
 In Step 4 switching works fine. Markup is OK
 In Step 5 markup is shown OK
 In Step 6 after the 1st pressing no elements are selected. Counter still displays "3 of 3" 
           after the 2nd-3rd pressings no elements are selected, counter says "2 of 3", "3 of 3"
 In Step 7 makup is blank

ER:  
 In Step 6 "Search HTML" should switch to elements and update the counter correctly
 In Step 7 markup should be shown

Note:
1) Looks like I can't reproduce it with searching with selectors, even if I use selector for exactly
   those 3 nodes. So presumably this is specific to "Search text" feature (implemented in bug 835896)
2) Firefox DevEdition 45 (ID 20151222004010) is affected

This is most likely due to the way the page is restored from the bfcache. I'm guessing that the search is still being done on the previous page. There is an error in the console when searching after going back:

Protocol error (unknownError): TypeError: node.defaultView is null
inspector-search.js:63

Not reproducible on the last build before bug 835896. Reproducible on the 1st build after bug 835896.

works fine for me now. Might be related to all the work around fission/EFT
