However, the field can still be navigated using the arrow keys and be highlighted. Also the data is still there and can still be match to the pages data (in other words the find functionality still works). The data can be recovered by selecting all the text and pasting it to a text file or by bringing the fields character count less than 43,685. Spaces seem to hold a special attribute as for every character that is replaced with a space out of the 43,685 two spaces can be inserted before the defect is noted. Reproducible: Always Steps to Reproduce: 1. Create a plain text file with 43,684 continuous characters. 2. Copy and paste those characters into the find in this page input field. 3. Enter one more character and note that the field becomes blank. 4. Delete one character and note that the field's data becomes visible again. 5. Enter one space. Note the field's data is still visible. 6. Enter another space. Note the field's data becomes invisible again. 7. Repeat steps 5 and 6 as need to confirm the ratio is one non-space character to two space characters. Actual Results: The input field's data becomes invisible. Expected Results: The input field to limit the number of characters it can handle and display all characters until that limit is reached. One might believe this is an unrealistic amount of data to input into this field so here is a general case to consider... Searching for a large snippet of text from a very large web page such as a PDF file being viewed as HTML (i.e. a microprocessor instruction manual).

This might be a dup of one of bug 302294's other dependencies.

This seems to be fixed (probably by fix for bug 237085) -> worksforme. Please reopen if you can reproduce this with a recent nightly build.
